Overview
Our please knock before entering sign printing starts with one job: the sign asks people to knock first and wait before walking in. It earns its place in offices, treatment rooms, staff rooms and meeting rooms.
Where it goes
Right on the door at eye level, so it is the last thing people see before they reach for the handle.
Before you order please knock before entering sign printing, think about how far away people will be. Rule of thumb from ISO 3864-1: each 25 mm on the short side of the sign gives roughly a metre of reading distance. That makes 200 x 50 to about 2 m, 250 x 75 to about 3 m and 297 x 100 to about 4 m. That suits doors, walls and counters, where people stand close.
Reading the sign
It reads "Please Knock Before Entering". Blue circle means "you must". It is an instruction, not advice.
Please knock before entering sign printing: which material
Our please knock before entering sign printing comes on three kinds of board:
- 3mm Foamex, a rigid PVC foam board that screws or sticks up easily and is happiest indoors or out for a season
- 3mm Dibond, aluminium skins on a solid core, the one to pick for a sign that stays outside for years
- self-adhesive vinyl, which sticks flat to smooth walls, doors, glass and machine guards
Inside, Foamex or vinyl does the job. Outside for the long haul, go Dibond.
Keep the instruction short. People read these in passing, often with their hands full.
The Health and Safety (Safety Signs and Signals) Regulations 1996 set the look of a "must do" sign: a blue circle with a white symbol or instruction.
Send a print-ready PDF, build it in the online designer, or pay for our artwork service (you get 1 design and 2 rounds of changes). Whichever you pick, a person checks the file before it prints. Each please knock before entering sign printing job is printed to order and sent out from the UK. We charge £7.95 to send it anywhere on the UK mainland, and nothing once your goods come to £100 or more after discounts. The Highlands add £10, and addresses in Northern Ireland, the Scottish islands, the Isle of Man, the Channel Islands, Scilly or the Isle of Wight get a quote. Full details are on the delivery page.

Which size do I need?
A safety sign must be large enough to read from where people will see it. Our conservative guide, based on the distance-factor method in ISO 3864-1, is about 1 metre of viewing distance for every 25 mm of sign height (the shorter side). Use it with your own risk assessment.
| Size | Readable from up to about |
|---|---|
| 200 × 50 mm | 2 m |
| 250 × 75 mm | 3 m |
| 297 × 100 mm | 4 m |
Well lit or internally lit signs can be read from further away; dim areas need larger signs.
Questions
Quick answers about please knock before entering sign printing.
How big should the Please Knock Before Entering sign be?
Think about the furthest point someone needs to read it from. For "Please Knock Before Entering", 200 × 50 mm for readers up to 2 m away, 250 × 75 mm for readers up to 3 m away and 297 × 100 mm for readers up to 4 m away. Those distances assume ordinary light, so if it is gloomy or people are driving past, step up one size.
Is there a standard pictogram that says "Please Knock Before Entering"?
ISO 7010 has nothing specific to this message, so the sign uses the general mandatory action symbol, M001, alongside the text.
Where is the best place to put the "Please Knock Before Entering" sign?
Put it on the door or at the counter, at eye level where visitors stop. Check nothing will stand in front of it, like open doors, stacked stock or parked vans.
Does the law say I must put up a Please Knock Before Entering sign?
The format comes from the Health and Safety (Safety Signs and Signals) Regulations 1996: a white symbol or instruction inside a blue circle, meaning something people must do. Your risk assessment is what decides the exact positions for "Please Knock Before Entering".
Will the Please Knock Before Entering sign survive outdoors?
Yes, if you order it in Dibond, which cope with rain. Foamex is better kept indoors or somewhere sheltered. Pick the material in the options before you order.
Why is the Please Knock Before Entering sign in these colours?
A blue circle means an action people must take. The "Please Knock Before Entering" sign uses that standard layout, so people read its meaning before the words.
Is the price shown for the "Please Knock Before Entering" sign the full price?
Yes, for the goods. What the page shows is what you pay for the goods at checkout. Postage to the UK mainland is £7.95 per basket, not per item, and free when your goods total £100 or more.
Asked by buyers
How cheaply can I get hold of the Please Knock Before Entering Sign?
Picked the way the page first loads, with 200 × 50 mm and self-adhesive vinyl, the Please Knock Before Entering Sign comes to £3.81. Any other mix of options, a faster turnaround included, gets its own price the moment you choose it, and that figure is what you pay at checkout. Only delivery is left to add. On its own the opening price of £3.81 would add £7.95 for mainland delivery; reach £100 of goods and that goes to zero.
Which turnaround speeds can I choose for the Please Knock Before Entering Sign?
Allow 6 working days on Saver, 4 on Standard or 2 on Express before the Please Knock Before Entering Sign is handed to the courier, based on the options the page opens with. Weekends and bank holidays are not counted, and nothing starts until the order is paid and the artwork is confirmed. Pick another size or material and the days beside each speed update, sometimes by a day. After it leaves us, the courier normally delivers in one to three working days and you get the tracking link by email.
Which artwork services are offered with the Please Knock Before Entering Sign?
Several routes, all chosen under Artwork on this page. Send your own finished file (no charge), we set your words and logo on a tidy layout, called typesetting (£15), we design it from your brief (£35), we redraw a blurry or low quality logo as sharp vector art (£30) or we create a brand new logo (£50). Typesetting and design from a brief each come with one first draft and two rounds of changes. The fee is the same whatever quantity you order and shows separately in the basket. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. On this page, Please Knock Before Entering Sign starts from £3.81.
Which is the smallest and which the biggest sign I can order here?
The table has 3 sizes. At the small end, 200 × 50 mm costs from £3.81; at the top, 297 × 100 mm costs from £4.26. Each figure is for the cheapest set of options at that size. Unsure? Measure where it will go and check the view from the spot people will stand. Sizes for this sign go from 200 × 50 mm at the small end to 297 × 100 mm, 3 in all. On this page, Please Knock Before Entering Sign starts from £3.81.
Which size of the Please Knock Before Entering Sign can people read from further away?
Rough reading distances for "Please Knock Before Entering": about 2 m for 200 × 50 mm, 3 m for 250 × 75 mm or 4 m for 297 × 100 mm. The rule of thumb behind them: each 25 mm of height buys roughly one metre of distance. If the light is poor, or people pass quickly on foot or at the wheel, go for the next size up. The figures use the distance factor from ISO 3864-1, and your own risk assessment should settle the final choice.
Where is the best spot for a Please Knock Before Entering Sign?
Picture someone arriving at an office, a shop, a school or a club house who needs to see "Please Knock Before Entering". Fix it level with people's eyes on the way towards the hazard or area it covers, clear of doors that swing open and of stacked stock. Give it decent light and a clear line of sight, with nothing parked, stacked or swinging open in front of it. Keep a short list of where each sign went: it slots into your risk assessment records and makes the odd walk-round check quick. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex.
What message is a Please Knock Before Entering Sign giving?
Start with the symbol on "Please Knock Before Entering". M001 is the ISO 7010 pictogram for general mandatory action sign, so even someone without much English gets the gist at a glance. The design follows the mandatory sign pattern (a solid blue circle), used to tell people something they have to do. That colour and shape code is laid down by the 1996 Safety Signs and Signals Regulations. Typical spots: an office, a shop, a school or a club house.
I need several signs, some in different sizes. How do I buy them?
Each price on the page is for a single sign in the size and material chosen. Put the number you want in the box beside Add to basket and the total multiplies. For a different size or material, add it as a separate line; the basket keeps them apart. An artwork fee is charged once per line, whatever the quantity, and choosing to reuse the artwork from another item in your basket costs nothing more. Very large runs can go through Get a quote. Nothing is printed ahead of time: each sign is made to order for you. Before delivery, this sign costs from £3.81. For reference, Please Knock Before Entering Sign is listed in 3 sizes, the smallest being 200 × 50 mm.
How much for the biggest size, 297 × 100 mm?
From £4.26, with the cheapest settings and the Saver service. Material by material, it is 3mm Foamex at £25.15, 3mm Dibond aluminium composite at £37.23 and self-adhesive vinyl at £4.26. Add £7.95 for UK mainland delivery, or nothing at all once the goods reach £100. Select it on the page and swap materials, finishes and speed to watch how the figure moves.

Material choices for Please Knock Before Entering Sign: 3mm Foamex, 3mm Dibond aluminium composite or self-adhesive vinyl.
Can I mix different safety signs in a single order?
You can. Each sign gets a separate basket line, with whatever size and board suit it, and you pay once at the end. Delivery is charged per order, not per sign: £7.95 to the UK mainland, or free once the goods come to £100 or more. For "Please Knock Before Entering" the sizes are 200 × 50, 250 × 75 and 297 × 100 mm.
I am not a business. Can I buy just one sign?
Of course. Anyone can order, with no trade account and no minimum beyond one. Prices for the Please Knock Before Entering Sign begin at £3.81, checkout works without an account and you pay by card. Parents, clubs, churches and small shops order single items all the time. On its own the opening price of £3.81 would add £7.95 for mainland delivery; reach £100 of goods and that goes to zero.
Could the total go up after I reach the checkout?
No surprises: what the page shows for this sign is the goods figure you pay at checkout. Delivery is the one extra, £7.95 to a UK mainland address, and it drops away when the goods reach £100 after discounts. Paid artwork help shows up as its own basket line, so you can check each amount before paying. Nothing is printed ahead of time: each sign is made to order for you. Sizes for this sign go from 200 × 50 mm at the small end to 297 × 100 mm, 3 in all. On its opening option, Please Knock Before Entering Sign leaves us after 6 working days on Saver.
Our event is close. Can the Please Knock Before Entering Sign be rushed?
Yes. Choose Express and the Please Knock Before Entering Sign can be on the way in 2 working days on the opening option, for £5.06, where Saver is £3.81 and takes 6 days. Then give the courier one to three working days, and send the artwork with the order, because the clock does not run until the file is sorted. If the date is really tight, message us on the Contact page before paying and we will tell you honestly.
Can the wording on a Please Knock Before Entering Sign be changed, or our logo added?
Yes. To reword "Please Knock Before Entering" or add a logo, pick the typesetting option (£15) for your text and logo on a clean layout, or the design-from-your-brief option (£35), then send us the details. Both paid options include one first draft and two rounds of changes. Uploading your own print-ready file costs nothing, and someone on our team looks it over before printing. Leave the safety symbol and its colours untouched, though: altering them makes the meaning less clear. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex.
Can I send a Word or Canva file for the Please Knock Before Entering Sign?
Word, PowerPoint and Canva are a fair place to start, but export a high quality PDF from them before uploading. Our first choice is always a PDF at the ordered size with fonts embedded or outlined, followed by AI, EPS or SVG, then high resolution JPG, PNG or TIFF. You can add three files, each up to 25 MB, on this page, or upload them after ordering from the email we send. Make the artwork for this sign the same size as the one you order, such as 200 × 50 mm.
Someone else is putting our file together. How does it reach you?
Easiest route: they send the finished file to whoever placed the order, and it gets uploaded after ordering. Up to 3 files of 25 MB each are fine. They can also reach us through the Contact page, as long as they quote your order number so it lands on the right job. Production waits for the checked file, so a late file means a later dispatch date. Make the artwork for this sign the same size as the one you order, such as 200 × 50 mm. Sizes for this sign go from 200 × 50 mm at the small end to 297 × 100 mm, 3 in all. On this page, Please Knock Before Entering Sign starts from £3.81.
Will anyone look at my file before it is printed?
Yes, a real person on our team opens every uploaded file and checks the size, the bleed and the resolution. If something is off, you hear from us before anything is made. We print what you send, though, so read the spelling, numbers and dates yourself as well. Making starts when the order and the file are both confirmed. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. Make the artwork for this sign the same size as the one you order, such as 200 × 50 mm. For reference, Please Knock Before Entering Sign is listed in 3 sizes, the smallest being 200 × 50 mm.
I am not a designer. What if the file I send turns out to be unusable?
That is why a person looks at every upload before anything is printed. Typical snags are a document at the wrong size, missing bleed, blurry photos and words sitting too near the trim. If we spot one, we explain what to change and you send a fresh file. Or hand it over to us: for £15 our typesetting places your wording and logo on a neat layout, with one first draft and two rounds of changes. Make the artwork for this sign the same size as the one you order, such as 200 × 50 mm. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex.
How many pixels does a photo need to print well on this sign?
Close-up items need about 300 dpi at full size. So a 297 × 100 mm layout wants about 3,508 by 1,181 pixels. Keep lettering and logos as vectors if you can. An image copied off a web page or a social post rarely has enough pixels; if yours looks likely to print soft, our file check flags it. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. On this page, Please Knock Before Entering Sign starts from £3.81.
What thickness is the Please Knock Before Entering Sign, and does it feel sturdy?
Three millimetres, whichever board you go for. Pick self-adhesive vinyl instead and you get a thin film that lies flat against whatever you stick it to. Dibond feels stiff because a plastic core is sandwiched between two thin aluminium sheets, yet it is still simple to screw or stick up. Foamex is foamed PVC, so it weighs very little in the hand. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. Material choices for Please Knock Before Entering Sign: 3mm Foamex, 3mm Dibond aluminium composite or self-adhesive vinyl.
Does the Please Knock Before Entering Sign come in a peel-and-stick version?
It does. Pick self-adhesive vinyl from the material list and it comes as a peel-off sticker. That is handy on a glass shop door, a classroom cupboard, a machine or a smooth painted wall, anywhere screwing a board up would be awkward. Wipe the spot, let it dry, then press it down from the centre outwards to push the air away. On rough brick or dusty surfaces, a board will hold better. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. For reference, Please Knock Before Entering Sign is listed in 3 sizes, the smallest being 200 × 50 mm.
We are putting up a full set of signs at our premises. Which ones sit well next to this one?
A school corridor, a shop floor or a club house rarely needs just one notice. Two that often go up beside this one: Keep to Walkways Sign and Wear Safety Helmet Sign. Keep every sign in one board type so the set matches, look up sizes and prices on each page, then check out once: one delivery charge for the whole basket, free over £100 of goods. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex.
Will a Please Knock Before Entering Sign cope with rain and wind outdoors?
Rain is rarely the problem for "Please Knock Before Entering"; sunshine is. Every printed sign fades slowly in strong sun, so make a habit of checking outdoor ones and renew any that have faded too far. Dibond is the board to pick for a permanent outdoor home. Foamex copes with a covered spot but prefers life indoors. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex.
It gets dark early in winter. Can people still read the Please Knock Before Entering Sign in the evening?
Not in pitch darkness. Pick Foamex, Dibond or vinyl sticker and it is the same story: nothing on this page reflects headlights or glows by itself. Fix it where a street light, porch light or security lamp already shines, or fit a small light above it. Where a risk assessment asks for photoluminescent or reflective signs, those need to come from a specialist maker rather than from us. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. Nothing is printed ahead of time: each sign is made to order for you. On its opening option, Please Knock Before Entering Sign leaves us after 6 working days on Saver.
What is the easiest way to put up a Please Knock Before Entering Sign?
To mount "Please Knock Before Entering" on a wall, drill a hole near each corner of the board and screw it on with a washer under each head; stop once it feels snug, as Foamex in particular does not like being overtightened. Where drilling is not wanted, say on a painted door or a smooth wall inside, double-sided foam tape or sticky pads hold it well. For a fence, make a hole at each corner and loop cable ties through. The vinyl one needs no tools: peel off the backing and press it on once the surface has been wiped and dried. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex.
How would I decide between Wear Safety Helmet Sign and Please Knock Before Entering Sign?

Do we legally have to display a Please Knock Before Entering Sign?

Tell us quickly through the Contact page, quoting your order number. Before production starts we can take a corrected file, or cancel and refund the whole order. After that it cannot be changed.

Leave the symbol and colours as they are, so the meaning is clear whichever language someone reads. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. Make the artwork for this sign the same size as the one you order, such as 200 × 50 mm.
Some of our visitors have poor eyesight. Will this sign be easy for them to read?
Three things help most: strong contrast between the words and the background, a plain bold font, and a size that matches how far away people will be. Our standard safety sign layouts use the high-contrast colour pairings laid down for safety signs. Mount the sign at eye height, where it is well lit and not catching glare, and keep the message short. Make the artwork for this sign the same size as the one you order, such as 200 × 50 mm. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. For reference, Please Knock Before Entering Sign is listed in 3 sizes, the smallest being 200 × 50 mm.

We can still help. Put the size you need, the material and the quantity into the quote request form and we will send a price. For reference, the listed range ends at 297 × 100 mm, and that size costs £4.26 or more. Bear in mind that anything past A0 goes by oversize courier, a one-off £15 on the order. Sizes for this sign go from 200 × 50 mm at the small end to 297 × 100 mm, 3 in all. On this page, Please Knock Before Entering Sign starts from £3.81.
The spot gets full sun all afternoon. Could this sign warp in the heat?
Foamex can, Dibond will not. A big, thin Foamex board warms up in direct sun and may bow, especially with fixings only at the corners. Dibond has aluminium faces and keeps its shape, so it is the sensible pick for a long-term outdoor sign. With Foamex, more fixings across a flat wall, or a thicker board, helps it stay straight. For this sign, the material can be self-adhesive vinyl, 3mm Dibond aluminium composite or 3mm Foamex. Before delivery, this sign costs from £3.81. On this page, Please Knock Before Entering Sign starts from £3.81.

We publish every genuine review, good or bad, exactly as it was written. We never edit reviews or choose which ones to show. The only reviews we hold back are spam, abuse, or ones that include personal details like a phone number or email address.
The star rating is the average of every published review. We never pay for reviews or give discounts or gifts in return for them.
Reviews show the reviewer's first name and initial. To have your own review taken down, contact us.
