YouTube Image Sizes: Thumbnails, Banners & More (2026)
Your thumbnail is the single biggest factor in whether anyone clicks your video — and YouTube's banner has one of the trickiest safe areas on any platform. Here is every image size YouTube uses in 2026, with the exact dimensions that survive cropping on TVs, desktops, and phones.
| Use | Dimensions | Ratio | Notes |
|---|---|---|---|
| Video thumbnail | 1280 × 720 px | 16:9 | Minimum width is 640px, but always upload 1280 × 720 — thumbnails get shown large on TVs and search results. |
| Channel profile picture | 800 × 800 px | 1:1 | Displays as a circle at 98px in most places — keep the subject centered and avoid corner details. |
| Channel banner | 2560 × 1440 px | 16:9 | Only the central 1546 × 423 'safe area' shows on every device — put text and logos there or they vanish on mobile. |
| Shorts | 1080 × 1920 px | 9:16 | Full-screen vertical; the right edge and bottom get covered by like/comment buttons and the title. |
| End screen elements | 1280 × 720 px | 16:9 | End screens overlay the last 5-20 seconds of your 16:9 video — video thumbnails used here should match the standard 1280 × 720. |

Pro Tips
- Thumbnails must be under 2MB — a compressed JPG at 1280 × 720 leaves plenty of room for quality.
- Design banners inside the 1546 × 423 safe area first, then extend the background outward to 2560 × 1440.
- Test thumbnails at small sizes: most viewers see them at roughly 360px wide on a phone, so oversized text wins.
- Use PNG for thumbnails with sharp text overlays; YouTube recompresses less visibly than social feeds.
Frequently Asked Questions
What is the minimum YouTube thumbnail size?
YouTube requires a minimum width of 640px, but the recommended upload is 1280 × 720 at 16:9. Anything smaller gets upscaled on TVs and large displays, which makes text noticeably soft.
Why does my channel banner look cut off on mobile?
The 2560 × 1440 banner is cropped differently per device: TVs show all of it, desktop shows a wide strip, and mobile shows only the central 1546 × 423 safe area. Keep every important element inside that safe zone and the crop stops mattering.
