Make a poster that actually works
Your poster gets about two seconds from a driver at 40 km/h. Design it for that, and it becomes the single highest yield thing you do.
The three things that matter most
- 01
One enormous word
LOST, filling the top third of the sheet. That word is what makes someone's eye stop. Everything else is read afterwards, if at all.
- 02
One photo, one feature
A clear daylight photo and one distinguishing feature in words. Not a paragraph of description, and not four cute photos from your phone.
- 03
A number you can read from a car
Digits large enough to read at a glance and remember at a red light. Tear off tabs are a bonus, never the primary plan.
Design for two seconds, not two minutes
Almost every homemade lost pet poster fails the same way. It is written as a letter to a careful reader, and then stapled to a pole that people pass at speed.
The person who finds your pet is usually not searching for it. They are driving to work, walking a dog, or taking the bin out. Your poster has to interrupt them, and it gets one glance to do it.
That means high contrast, very few words, and a ruthless hierarchy: the word LOST, then the photo, then the phone number. If an element does not help one of those three land faster, take it off.
What goes on the sheet
In order, top to bottom, on a single sheet in landscape or portrait:
- LOST in the largest type that fits, filling roughly the top third
- DOG or CAT, almost as large. People filter by species before anything else
- One clear photo, daylight, showing the whole animal against a contrasting background
- One distinguishing feature in a short phrase: white left paw, notched right ear, blue collar
- The neighbourhood where the pet was lost, not your street address
- Your phone number, in very large digits
If you want to add the word REWARD, add the word and not the amount. A stated amount attracts people who want the money more than they want to help, and it gives a scammer a figure to negotiate against.
What to deliberately leave off
What you leave off protects you as much as what you put on protects your pet.
- At least one identifying detail. Keep a scar, a marking or a collar tag out of every public post so you can ask a caller to describe it.
- Your home address. The neighbourhood is enough for someone to know where to look.
- Your full name. A phone number is all a finder needs.
- A reward amount. See above.
- Long paragraphs of description. Nobody reads them, and they hand a scammer a script.
Some people put the pet’s name in large type hoping a finder will call it. For a frightened animal that usually backfires, and for a cat it almost always does. Keep the name small or leave it off.
Where to put them, and how to make them last
Placement matters as much as design. Aim for the places where people are already slowing down or standing still.
- Major intersections near where the pet went missing, at driver eye height
- Stop signs, crosswalks and roundabouts where cars pause anyway
- Trailheads, park entrances, off leash areas and dog walking routes
- Vet clinics, pet stores, corner stores, cafes and community boards
- The centre of your sighting cluster, once one appears
Slide each sheet into a clear plastic sleeve, or cover it completely front and back with wide packing tape. An unprotected poster is unreadable after one wet day, which is most of the Canadian year.
Check your municipal sign bylaw before you start. Many Canadian cities restrict what can be attached to utility poles and street furniture, and some remove posters on sight. Zip ties on approved boards do less damage than staples, and when your pet is home, take every poster down.
Do this, not that
Do
- Put LOST in the largest type on the sheet
- Use one clear daylight photo
- Name the species in large type
- Weatherproof every single poster
- Post at intersections at driver eye height
- Take them all down when the search ends
Do not
- Write a paragraph of description
- Print a reward amount
- Include your home address or full name
- Use four small photos instead of one large one
- Publish every identifying feature you have
- Rely on tear off tabs as the main contact route

Scams that target posters
Your poster is public, and some people read it looking for a mark rather than a match.

Posters matter less for cats than a slow physical search. Here is what does work.
