Running the same creative everywhere wastes reach. Here is the 2026 cheat sheet of ad sizes and aspect ratios your campaigns need — and how to produce all of them at once.
The aspect ratios that matter
- 9:16 (1080×1920): Reels, Stories, TikTok, YouTube Shorts.
- 1:1 (1080×1080): Meta and Instagram feed.
- 4:5 (1080×1350): highest feed real estate on mobile.
- 16:9 (1920×1080): YouTube in-stream and landscape display.
- Google Display: 300×250, 336×280, 728×90, 300×600, 160×600.
Design once, resize automatically
Instead of rebuilding each size by hand, generate a master concept and let AI re-render every aspect ratio with the layout and text repositioned for each canvas.
Don't crop — recompose
Naive cropping cuts off logos and text. AI resizing recomposes the creative so the message stays intact at every size.
Render every ad size free from a single brief.
