The TikTok thumbnail size is 1080x1920 pixels with a 9:16 aspect ratio. That's the short answer. Here's everything else you need to know to design thumbnails and slideshow covers that display perfectly across all TikTok surfaces.
TikTok Thumbnail Size: Quick Reference
- Dimensions: 1080 x 1920 pixels
- Aspect ratio: 9:16 (vertical portrait)
- File format: JPEG or PNG
- Maximum file size: 50MB recommended
- Minimum resolution: 720 x 1280 pixels (1080x1920 strongly preferred)
Where TikTok Thumbnails Display
Your TikTok thumbnail (cover image) appears in multiple places, each with different display sizes:
For You Feed
Thumbnails show at roughly 375x667px on most phones before the video plays. High contrast and bold text are essential at this size.
Profile Grid
In your profile, videos display as square thumbnails cropped from the center of the 9:16 frame. Design your thumbnail so the key visual is centered—don't put important elements at the top or bottom where they may be cropped.
Search Results
Thumbnails show at approximately 200x356px in search. At this size, small text becomes unreadable. Only large, bold text (40pt+) is visible.
Explore and Trending
Similar to search results. Prioritize a single clear visual element that reads at thumbnail size.
Safe Zone for TikTok Thumbnails
TikTok overlays UI elements on the video frame: the right-side action buttons (like, comment, share), the bottom username and caption, and the top notification bar. Keep your main visual content within the center 60% of the frame vertically and the left 80% horizontally.
Safe zone dimensions: Keep critical elements within roughly 810x1440px of the center of a 1080x1920 canvas.
TikTok Thumbnail vs. TikTok Slideshow Cover
For regular videos: the thumbnail is a single frame you select from the video, or a custom image you upload. For TikTok photo slideshows (Photo Mode): the first image in the carousel IS the thumbnail. There's no separate cover upload—your first slide is what appears in the feed and on your profile.
This means for photo carousels, your first slide needs to do double duty: hook viewers and display well as a static thumbnail at small sizes.
How to Set a Custom TikTok Thumbnail
For Videos
1. Upload your video in TikTok. 2. In the post screen, scroll down to 'Cover'. 3. Drag the slider to choose a frame, or tap 'Upload cover' to use a custom image. 4. Your custom image must be 1080x1920px JPEG or PNG.
For Photo Slideshows
The first slide is automatically the cover. You cannot upload a separate thumbnail for Photo Mode posts. Design your first slide as both a hook and a thumbnail.
Designing TikTok Thumbnails That Get Clicks
Typography at TikTok Scale
At the 200px search thumbnail size, only 40pt+ fonts are readable. TikTok's own text overlay styles—outline, highlight, and shadow—are specifically designed for readability on mobile screens. Use them.
TikTok Sans, TikTok's native font, is available in Hooksie's editor. It's the same font TikTok uses internally and reads well at all thumbnail sizes.
Color and Contrast
Light backgrounds with dark text or dark backgrounds with light text. Avoid colors in the 40–60% lightness range—they blend into TikTok's white and dark-mode backgrounds.
The One-Element Rule
Your thumbnail has one job: make someone tap. Pick one dominant visual element. Face, product, or text—not all three. Busy thumbnails underperform at small sizes.
TikTok Thumbnail Size vs. Other Platforms
- TikTok: 1080x1920px (9:16)
- Instagram Reels: 1080x1920px (9:16) — same dimensions
- YouTube Shorts: 1080x1920px (9:16) — same dimensions
- YouTube standard: 1280x720px (16:9) — landscape, very different
- Instagram Feed post: 1080x1350px (4:5) — slightly different ratio

Frequently Asked Questions
Can I use a horizontal image as a TikTok thumbnail?
No. TikTok requires portrait (9:16) orientation. Horizontal images are not supported for video thumbnails or slideshow covers.
What resolution is best for TikTok thumbnails?
1080x1920px. Never go below 720x1280px or you'll see quality degradation, especially on high-DPI screens.
Does TikTok compress thumbnails?
Yes, TikTok compresses all uploaded images. Starting with a higher resolution (1080x1920) minimizes visible quality loss after compression.
Can I change a TikTok thumbnail after posting?
Yes, for videos. Go to your post → three-dot menu → Edit → Cover. For photo carousels, the first slide is the permanent cover and cannot be changed after posting without deleting and reposting.
