Twitter (X) Bio Character Limit 2026 (160)

The twitter bio character limit is 160 characters, and it's one of the few specs on the platform that hasn't moved in years, including through the rebrand from Twitter to X. While post length, video limits, and subscription tiers have all shifted repeatedly, the bio field has stayed exactly where it was.

X bio character limit, and what counts against it

Field	Limit
Bio	160 characters
Links in bio	Count at full length (not shortened)
Emojis, hashtags, mentions	All count toward the total

That link detail catches people off guard: unlike in a regular post, where a URL counts as a fixed short length regardless of its actual size, a link pasted into your bio counts every character. A long URL can eat a third of your available space before you've written a word about yourself.

How long can a Twitter bio be, used well

With a firm 160-character ceiling and links costing full price, a workable structure keeps things tight:

1. Lead with what you do, in as few words as possible.
2. Add one credibility or personality signal if there's room, a role, a location, or a specific focus.
3. Skip the link unless it's essential, or use a shortened URL if your bio needs the space for anything else. Most profiles already show a separate website field outside the bio text itself, worth using instead of burning bio characters on a link.

Why this number has stayed put

X has changed a lot about the product since the rebrand, subscription tiers, video length by tier, algorithmic feed changes, but the bio field is basic profile infrastructure rather than a feature tied to engagement or monetization. There's little product incentive to touch it, which is likely why it's remained untouched while flashier specs shift around it.

A quick before-and-after

"Marketing professional | Coffee enthusiast | Dog dad | Views my own" uses most of its length on labels that don't tell a visitor anything useful. "I write about B2B marketing for SaaS founders. Ex-agency, now in-house." covers roughly the same character count while actually answering who you are and why someone might follow you. The second version does more work in the same space.

Common mistakes inside 160 characters

• Front-loading a name or title that's already shown elsewhere on the profile, wasting space repeating information.
• Cramming in every credential instead of the one or two that matter most to the audience you want to attract. Skip a joke that only makes sense with context the bio doesn't have room to provide.

Keeping your whole profile in sync

If you're also writing posts for the account, the Twitter character counter covers the separate (and more frequently hit) post length limit, a different number from the bio covered here, worth checking independently since the two are easy to confuse.
