One table to check before you paste

Name change limits by platform

Every platform counts length differently and limits how often you can rename. This table gathers the documented numbers at the time of writing; the live field in each app remains the final check.

The table

Figures come from public help pages and in-app screens and can change without notice. Found a difference? Use the contact page.

How length is counted

Some fields count user-perceived characters, others count code points or UTF-16 units. A single emoji can be one, two or more depending on the platform, and a combining mark adds a count without adding a visible letter. The Compatibility Lab shows all three counts for any string and compares them against this table.

Cooldowns matter more than limits

Platforms with cooldowns — Instagram, TikTok, YouTube, Roblox, Riot — punish mistakes with a wait. Preview the exact string, check it in the lab, and change once.
