I check Bluesky character count before I post when the draft has a link, a long first sentence, or a profile update that I do not want to rewrite inside the composer.

Use TheBlue.social's Bluesky Character Counter when you want to paste a draft and check posts, bios, display names, and image alt text in one place.

The useful habit is simple. Check the draft early, then edit before the composer forces a rushed rewrite.

Start with the post limit

Bluesky post text is defined in the official app.bsky.feed.post lexicon. The text field has a maxGraphemes value of 300.

That means I treat 300 as the hard ceiling for the visible text of a post.

I rarely write to 300. If a post lands at 297 characters, I assume it is fragile. One extra word, one emoji, or one clearer phrase can push it over.

My comfortable range is lower.

  • under 180 characters for a quick observation
  • 180 to 240 characters for a useful post with context
  • 240 to 300 characters only when the detail actually matters

Long posts can work. At the edge of the limit, every phrase has to earn its space.

Count the draft before editing it down

I paste the draft into the counter before I start trimming.

At 420 characters, I skip adjective trimming and split the idea.

At 320 characters, I look for one sentence doing two jobs.

At 285 characters, I leave it alone unless it feels crowded.

The count changes the edit.

Here is how I read the count.

420 characters -> make it a thread or pick one idea
320 characters -> cut the setup
285 characters -> tighten only if the post feels slow

The count tells me which edit is worth making.

Watch links before you write around them

Links make character checks annoying because the visible URL and the counted URL may not feel the same.

The character counter treats URLs as 22 characters in post drafts, then counts the rest of the text by graphemes. I still do a final check in the Bluesky composer before publishing anything important, especially if the post has multiple links or unusual punctuation.

My rule is simple. If the link is the point, keep the surrounding post short.

I usually write links with a simple shape.

  • one clear sentence before the link
  • no extra throat-clearing
  • one reason to click
  • no second link unless the comparison is the whole point

If I need a second link, I often move it to a reply. The first post stays cleaner, and the link preview has less competition.

Check profile fields separately

Bluesky profile text has different limits from posts.

The official app.bsky.actor.defs lexicon defines profile display names with a maxGraphemes value of 64 and descriptions with a maxGraphemes value of 256.

I check those separately because a good profile has a different job from a short post.

For a display name, I want these things.

  • the name people recognize
  • no decorative clutter
  • room for the handle to do its own job

For a bio, I want a tighter answer.

  • what I do
  • who it is for
  • one useful proof point or topic marker
  • no packed list of every interest I have ever had

A 256-character bio can still feel too long. The limit is the boundary.

Use the count to remove weak context

When a profile bio is too long, I remove the soft parts first.

Words like "currently," "mostly," "trying to," and "interested in" are often signs that the profile still needs a clearer decision.

I also cut repeated category words.

Weak version.

I write about product building, product marketing, and product growth for founders.

Cleaner version.

I write about product growth for founders.

The shorter version gives the profile more confidence and leaves room for a specific detail.

Treat alt text as accessibility

The official app.bsky.embed.images lexicon defines image embeds with an alt string for accessibility.

The character counter includes an image alt text box because alt text is part of the posting workflow. I use it to check whether the description is getting unwieldy.

Good alt text usually answers three questions.

  • what is in the image?
  • what detail matters for this post?
  • what text appears in the image, if that text is important?

I avoid repeating the whole post in the alt text. I also avoid using alt text as a hidden second caption. If the detail matters to everyone, it probably belongs in the visible post or a reply.

Check the draft in context

The number is only one part of the edit.

After the draft fits, I check the surrounding context. A tight post can still fail if the first line is vague, the link has no reason to be clicked, or the question asks people to do too much work.

I also compare the post against the thing I want someone to do next. A post asking for replies needs a little room for the question. When I share a tool, I need enough room to explain why the tool is useful. An article link needs a clean setup, not a mini version of the whole article. The count helps me keep that distinction visible before I publish.

I use the count to make room for the useful part.

  • a clearer noun instead of "this"
  • one concrete example
  • one reason the link matters
  • a softer ask when I want replies

If the draft has enough room, I spend it on clarity rather than decoration.

Keep a reusable scratch version

When I am writing several posts for the same topic, I keep one scratch version outside Bluesky.

That scratch version has three parts.

  • the plain claim
  • the useful detail
  • the link or call to reply

Then I test different versions in the counter.

One version might be better for replies because it asks a clean question. Another might be better for sharing a resource because it gets to the link faster. A third might work as a reply because it needs less setup.

The counter makes those versions easier to compare. I am not guessing which draft feels tighter while also fighting the character limit.

I keep the discarded versions too. A sentence that does not fit the main post can become a reply, an alt text note, or a follow-up post later. That matters when I am turning one article, product update, or support answer into several small Bluesky posts.

This also keeps me from treating the first draft as precious. If the best line costs 80 characters, I can keep it and rebuild the rest of the post around it. If the line is only clever, I cut it and move on.

For recurring announcements, I save the strongest version as a tiny template. The next time I need it, I start from a draft that already fits.

Leave room for the human edit

The best use of a character counter is before the final edit.

I paste the draft, check the number, then edit with a goal.

  • over by a lot -> split or rewrite
  • over by a little -> cut setup
  • close to the limit -> replace vague phrases
  • comfortably under -> stop trimming

The last one matters.

Over-trimmed posts sound like labels. If the post is clear and under the limit, I stop shaving it down.

My quick pass

Here is the pass I use before posting. It is short enough to run while drafting, and boring enough that I will use it.

  1. Paste the draft into the character counter.
  2. Check whether it is safely under 300 characters.
  3. If there is a link, confirm the draft still has room around it.
  4. Remove setup before removing useful detail.
  5. Read the post once out loud.
  6. Paste it into Bluesky and check the composer before publishing.

That final composer check stays in the process. A helper tool is useful because it lets me draft and fix problems earlier. The actual post still gets the last word.
