How to use the social post length and hashtag checker
Social platforms reject or truncate a post that runs a single character over the limit, and scheduling tools tend to surface the problem only at the last moment. Paste your draft here and the character count, hashtag count and remaining headroom update as you type.
The platform presets carry figures current in 2026 and are not official documentation. Limits change, and several platforms apply different ceilings to paid tiers or business accounts. Choosing a preset simply fills the limit box, which you can then overwrite with whatever your account actually allows. For anything important, check the platform help centre once before publishing.
Two character counts are shown. The first treats one emoji as one character, matching what a reader sees. The second is the UTF-16 length, which is what many input forms count, and it rises faster because most emoji occupy two units. When a post sits close to the limit, plan against the larger of the two.
Hashtags are counted as a hash followed by a run of non-space characters, so a tag broken by a space is not counted. The default ceiling of 30 follows the widely used Instagram figure and is editable like everything else here.
Frequently Asked Questions
They are 2026 figures kept as editable defaults, not official documentation. Paid tiers and account types can differ, so overwrite the limit box and confirm with the platform when it matters.
Most emoji take two UTF-16 units internally, so form-based counters charge them as two while readers see one character. Both numbers are shown; use the larger one when you are close to the limit.
