Pinterest Hashtag Limit Helper

Stay inside Pinterest's hashtag rules — count and audit instantly

Paste or type your hashtags and this tool counts them against Pinterest's enforced 20-hashtag limit, flags malformed and duplicate tags, and shows the character cost so your Pin description never gets suppressed or rejected.

How many hashtags can you use on Pinterest?

Pinterest allows up to 20 hashtags in a single Pin description. Going over the limit causes Pinterest to ignore or suppress the extra tags. The hashtags also count toward the 500-character description limit, so they share that budget.

Pinterest caps hashtags at 20 per Pin and quietly suppresses anything beyond that, while duplicates and malformed tags waste your budget and look spammy. This tool counts your tags against the limit, flags the problems, and hands back a clean, normalised string ready to paste.

How it works

The tool splits your input on spaces, commas, and new lines, normalises each token to a single lowercase hashtag, and then audits the set:

count       = number of valid, unique hashtags
over limit  = count > 20
duplicate   = same tag (case-insensitive) appears twice
malformed   = empty, contains spaces, or has no word characters
char cost   = total characters the hashtags add to the 500-char description

Because Pinterest matches tags case-insensitively, HomeDecor and homedecor collapse to one tag — counted once and flagged as a duplicate if both appear.

Tips and notes

The 20-tag ceiling is a hard limit, but Pinterest’s own guidance is to use only a focused handful of highly relevant tags; a packed list dilutes relevance and can reduce distribution. Remember the tags share the 500-character description budget, so keep them short. Use the cleaned output to drop duplicates and place your two to five strongest tags at the end of an otherwise keyword-rich description.
