Sticker Sizes: The Complete Guide (Print and Digital)

There are two sticker size questions, not one. On a screen, messaging apps converge on a square 512x512 pixels — WhatsApp and Telegram both use it — while print stickers are sized in inches or millimetres, with 2x2 in (50x50 mm) and 3x3 in (76x76 mm) covering most die-cut work at 300 DPI. VdoBloom’s chibi sticker tool at /dashboard/images/chibi-stickers/ outputs 512x512 animated stickers in the formats WhatsApp and Telegram accept.

Screen sizes first

Sticker pixels are small because the surface is small. A sticker on a phone occupies a fraction of a chat bubble, so the shapes that survive are big ones: an oversized head, a clear silhouette, a single expression. That is why most sticker art is drawn in a chibi or cartoon style, and why a detailed illustration loses its identity at 512 pixels wide.

Platform	Size	Format	Notes
WhatsApp	512x512	Animated WebP or PNG	Packs need at least three stickers; each sticker has a file-size cap (under 500 KB)
Telegram (static)	512x512	PNG or WebP	Square, transparent background
Telegram (video sticker)	512x512	WEBM with VP9 encoding	Three seconds maximum, silent loop
iMessage stickers	Up to 618x618	PNG or APNG	Square source art scales cleanly inside the limit
Discord emoji	128x128	PNG, GIF or WebP	Far smaller than a chat sticker; keep detail minimal
Slack emoji	128x128	PNG or GIF	Tight file-size limit, so flatten transparency carefully

Apps change their limits, so treat the table as the working standard rather than a promise: upload the largest square you have and let the app scale it down. A square source at 512x512 or above covers every row above without redesigning anything, which is why it is the size worth committing to.

Print sizes

Print stickers are usually die-cut — a shape cut from a sheet rather than a rectangle — and buyers pick from a short list of standard sizes. These are the ones most print shops list.

Use case	Millimetres	Inches
Small logo or reward sticker	38x38 mm	1.5x1.5 in
Everyday die-cut	50x50 mm	2x2 in
Product or packaging label	76x76 mm	3x3 in
Large single sticker	100x100 mm	4x4 in
Rectangular label	50x76 mm	2x3 in
Roll label	76x50 mm	3x2 in
Bumper sticker	292x76 mm	11.5x3 in

Sheets and packs use paper sizes instead of single-sticker sizes. A kiss-cut sheet — where the stickers are cut but the backing is not — is commonly 4x6 in (102x152 mm) or A6 at 105x148 mm, with A5 at 148x210 mm for larger sets.

Resolution, bleed and the two rules of print

Two numbers matter more than the size itself. The first is resolution: print work should be prepared at 300 DPI, which means a 2x2 in sticker needs 600x600 pixels and a 3x3 in sticker needs 900x900 pixels of source art. A 512-pixel sticker image is fine on a phone and soft on paper at 2 in, so generate at a larger size if the sticker is going to be printed.

The second is bleed. Die-cutting is not perfectly precise, and a sticker cut a millimetre off centre shows a white sliver along one edge. Add 2–3 mm of bleed around the artwork — background colour extending past the cut line — and keep anything essential well inside the cut. For transparent stickers, keep the artwork itself inside the cut line and let the bleed be transparent.

Two more print details are worth knowing before you send a file. Stickers are almost always cut with a contour line traced around the subject rather than as a rectangle, which is why a clean alpha channel matters: a background that is nearly white leaves a halo of pale fringe along the cut. If the artwork is going onto a product, agree the cut line with the printer rather than assuming it, and keep any element that must stay whole — a wordmark, a face, a number — a few millimetres inside it.

On screen the equivalent trap is file size. Animated stickers carry several frames, so a long animation with heavy transparency can pass a pixel-size check and still be rejected for being too large. Keep animated loops short — the tool builds a 25-frame loop — and keep the number of distinct colours down, which is also what makes the artwork read clearly at small sizes.

How to make sticker art with AI

VdoBloom’s chibi sticker tool is built around the 512x512 square that messaging apps want, and it produces the pack structure rather than a single image.

Open the chibi sticker tool and describe your character — the placeholder example is a sleepy office girl with a messy brown ponytail and a yellow raincoat. A photo is optional; if you provide one, the character is built from it. Descriptions are limited to 300 characters.
Pick the actions. Ten are available — wave, laugh, love, cry, thumbs-up, dance, angry, sleepy, thanks and shock — and up to six can be generated in one run. Three is the default, and three is also the minimum a WhatsApp pack needs.
Generate. Each sticker costs 5 credits, and a run takes roughly one to two minutes. The cost is shown before you start.
Download the pack. You get 512x512 animated WebP files for WhatsApp with a 96x96 tray icon, 512x512 WEBM video stickers for Telegram at three seconds maximum, and the same animations as GIFs for anywhere else — plus a zip so nothing has to be collected file by file.
For static or print stickers, take a different route. Generate the artwork at a large size in the image generator, remove the background for a clean cut-out, and prepare the file at 300 DPI with bleed for the printer.

Common mistakes

Designing at chat size for print. 512 pixels is plenty on a screen and thin on paper. Check the pixel count against 300 DPI before you send anything to print.
Fine detail and thin lines. Both vanish at small sizes. Bold shapes, high contrast, one subject.
Text in the artwork. Short words survive; anything longer turns to mush at 128 pixels, let alone in a chat bubble.
No bleed on die-cuts. Off-centre cuts are normal; without bleed they show as white edges.
Mixed shapes across a pack. Stickers in one pack look deliberate when the character, line weight and palette stay consistent. Changing style between actions makes the pack look assembled rather than designed.

Frequently asked questions

What size should a WhatsApp sticker be?

512x512 pixels, as an animated WebP or a PNG, with each sticker under the app’s file-size cap and at least three stickers in a pack. VdoBloom’s chibi sticker tool outputs exactly that size, with a 96x96 tray icon alongside it.

What size are Telegram stickers?

512x512 for both static stickers and video stickers. Video stickers use the WEBM format with VP9 encoding and loop for a maximum of three seconds — the same three-second cap the tool builds its animations to.

How big should a printed sticker be?

Most die-cut stickers are 2x2 in (50x50 mm) or 3x3 in (76x76 mm). Decide the printed size first, then multiply by 300 to get the pixels you need: 600x600 for 2 in, 900x900 for 3 in.

Can I print the stickers the tool makes?

You can, but generate larger artwork for print. The tool outputs at 512x512 for messaging, which is smaller than a 2 in print sticker needs at 300 DPI. Use the image generator for a large version, clean up the background, and add 2–3 mm of bleed before sending it to a printer.

How much does a sticker pack cost to make?

5 credits per sticker, so a three-sticker pack is 15 credits and a six-action set is 30. New accounts get 10 free credits with no card, and every cost is displayed before the run — plan and pack details are on the pricing page.

Open Chibi Stickers, describe a character, pick three actions and generate a pack — 15 credits gets you the WhatsApp WebP set, the Telegram WEBM files and the GIFs in one download. The chibi sticker walkthrough covers the workflow end to end, the background remover is the step that turns art into a clean cut-out for printing, and social media design is worth a read if the stickers are part of a larger brand set. The artwork itself is generated on GPT Image, which is worth knowing if you want to make a matching image at a larger size.
