TikTok slideshow size
The safest TikTok slideshow size is 1080 x 1920 pixels in a vertical 9:16 frame. Paid carousel ads are different: TikTok asks for 720 x 1280 vertical, 640 x 640 square or 1200 x 628 horizontal, JPG or PNG, and 100 KB or less per image.

Carousel ad rules TikTok enforces
- 2 to 35 images per carousel ad, of which up to 20 are shown
- JPG, JPEG, or PNG only
- 100 KB or less per image is TikTok's suggested file size
Sources, fetched 7 September 2026: carousel dimensions, image count, formats and file size from TikTok's carousel ad specifications; the in-feed video minimum from TikTok's video ad specifications; the Shop minimum from TikTok Seller Center. TikTok publishes no pixel spec for organic photo posts, so the two organic rows are our recommendation, not a TikTok rule.
Use vertical first
Most TikTok slideshows and photo posts should be built in a 9:16 frame.
Keep text centered
Avoid the lower-right and bottom edge where TikTok controls and captions sit.
Resize before design
Crop product photos before adding text so important details stay visible.
