Questions

What is the maximum video length on X?

2 minutes 20 seconds on a free account. Premium accounts can upload much longer videos.

Why is my video too big for X?

Over 512 MB, or longer than 2:20. Compress Video fits both, and cuts to the time limit if you choose.

What size is an X header?

1500 × 500 pixels, 3:1. The profile photo covers part of the bottom-left, so keep that area plain.
