Ad sizes for 2026, on every platform

A media plan names placements, and each platform publishes its own size for each one. Read one platform at a time and the list looks endless; put them side by side and most of it is the same handful of shapes. That is the useful way to read sizes: as shapes to lay out, each serving several placements at once.

Every value below was read from the platform’s own page on 27 October 2026. Each platform has its own page with every placement in full: Facebook, Instagram, TikTok, YouTube and Google Display.

Step 1Find each placement in the plan

The main placements on each platform, with the shape and size its own page lists:

Each platform’s page has the full list, including the smaller placements and the file limits: Facebook, Instagram, TikTok, YouTube and Google Display.

Step 2Group the placements by shape

Read across the table by shape rather than by platform, and the plan becomes a few layouts:

Make the tall master at 1440 × 2560 even for TikTok and Shorts, which list smaller sizes: it is the same shape, and one file then serves every tall placement in the plan.

Step 3Keep each shape clear where its platforms ask

Only some placements publish areas to keep clear, and they differ. On a tall layout that serves several, keep clear the union of them:

Meta’s bands are the only ones published as numbers, so lay the tall master out inside them first, then check it against TikTok’s safe zone file and a Shorts preview. What passes all three reads in full everywhere it runs.

Step 4Make one layout per shape, then fit the rest

Start with the shape that serves most of the plan, usually the tall one, at its largest size. Then lay out each other shape again around the same parts (photo, logo, headline, price, button, legal line) rather than cropping the first. A crop keeps one window of the master: from a square to a 728 × 90 banner it keeps 12% of the height, and from 4:5 to 9:16 it keeps 70% of the width.

• One layout per shape in the planNot one per placement.
• Each made at the largest size its placements listSo it only scales down.
• Every tall version inside the strictest bandsMeta’s numbers, then TikTok’s file and a Shorts preview.
• Every version carries the same price and legal lineChecked side by side before the set goes out.

File and length limits, side by side

Sizes are half of what gets an ad rejected; the other half is the file. Each platform’s limits for the main placements:

The two that catch people are opposite ends of the scale: Google’s 150 KB for a display image, which a photo saved at full quality can pass, and TikTok’s 500 MB for video, which a long, high-resolution export can pass. Export each with its limit in mind rather than one setting for everything.

Common mistakes

• Making one file per placement.Twelve placements are usually four or five shapes.
• Making the tall master at 1080 × 1920 because an old chart said so, then needing a sharper one for Meta.
• Cropping the tall version from the feed version.The logo and the price sit where the crop cuts.
