In-feed TikTok ads run in the same 9:16 feed as organic posts, so 1080 x 1920 vertical is the recommended size. Square (1:1) and landscape (16:9) are accepted, but vertical fills the screen and tends to perform best.
Keep ad videos short. Nine to fifteen seconds is the usual sweet spot, though you can run up to 60. Upload up to about 500 MB as MP4, MOV, MPEG, or AVI (a current-2026 ceiling worth re-checking in Ads Manager).
Spark Ads promote a real organic post, so they inherit that post's native size and sound. If you are duping a winning organic video into paid, Spark keeps it feeling native instead of like an ad.
