Making a 9:16 image from a phone photo

A typical 12-megapixel phone photo is 3024 × 4032. The largest 9:16 area you can cut from it is 2268 × 4032 pixels: crop to that, then scale it down to 1080 × 1920. Cropping first and scaling second keeps everything in proportion.

Frequently asked questions

What is the best size for TikTok videos?

Use 1080 × 1920 (Vertical, full screen, 9:16).

Which aspect ratio should TikTok videos use?

9:16. Crop to the ratio first and then scale to the size in pixels, so nothing is stretched or cut off unexpectedly.

Can I upload a 1920 × 1080 video to TikTok?

Yes, but a horizontal video only fills a band in the middle of a vertical screen. To use the whole screen, crop it to 9:16 (for example 608 × 1080 out of a 1080p frame) and scale it to 1080 × 1920, or reframe it while editing.
