Frequently asked questions

What is Social post preview?

Preview how your caption is truncated on Instagram, LinkedIn and X.

When would I actually use this?

Planning a post that fits: staying inside the character limit, exporting an image at the right size, and picking a slot when the audience is actually there.

What is the most common mistake?

Counting characters the way a text editor does. Emoji, accents and links are counted differently by each network — a link is often a fixed cost regardless of its real length.

How is Social post preview different from Social Media Post Time Optimizer?

They sit next to each other but answer different questions: Social Media Post Time Optimizer is the one to open when you need it to the conventional posting days for Instagram, Facebook, X, TikTok, LinkedIn, YouTube and six content niches, each with a cadence tip — flagged as a convention, not a measurement: replace it with what your own analytics say. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Social Media Character Counter is the closest one after this: Count characters against 15 social network limits — X/Twitter, Instagram, TikTok, LinkedIn, YouTube, Threads and more — with X's weighted rules (URLs = 23, CJK = 2) and a thread estimate.

What else is worth having open alongside it?

Social Media Image Size Guide and Social image resizer — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

Limits and image sizes come from each network's published specifications, which change without notice and sometimes differ between the web and mobile apps. Check the platform before a launch that matters.

How-toResizing an Image for Each Network Without Distorting ItMeasured on the resizer itself: Fill is a centre crop with no focal point, and a portrait photo loses 38.9 percent off the top for an X-sized banner. Plus the current published dimensions, each with the date it was checked.ExplainerWhen to Post, and Why the Answer Is Mostly Not the TimePublished best-time tables average over audiences that are not yours, and on a ranked feed posting time matters far less than it did on a chronological one. Compute your own audience's activity across time zones instead — six zones flatten the timing lever from a 94% swing to a 22% one — and see how many posts a real timing test needs.GuideSocial Image Sizes, and the One Crop That Survives EverywherePlatforms crop rather than letterbox, so an image is only safe if its subject sits inside the intersection of every ratio it will be shown at. That intersection has a closed form — the narrowest ratio divided by the widest — and it works out at 29.45% of the source for a realistic set. Geometry that does not expire, plus the pixel counts that do.ExplainerHashtags Are a Search Index, Not a MegaphoneA hashtag makes a post findable in a query, which is a different job from making it spread. Model the visibility a tag actually buys and the answer falls out: a tag's worth is its viewers-per-post-published, not its volume — so a very popular tag returns almost nothing and a specific one returns twenty-five times more.GuideEngagement Rate Formulas by Platform: Why the Same Post Scores 2% and 4.8%Engagement rate is not one metric. Divide by followers, by reach or by impressions and the same post returns three different numbers — and every platform defaults to a different denominator.GuideCharacter Limits That Actually Bite: Code Units, Code Points and GraphemesA character is three different things at once. One emoji with a skin tone is 1 grapheme, 2 code points and 4 UTF-16 units. Every count in this guide was measured in Node, plus why an SMS drops from 160 to 70 and why VARCHAR(255) is not 255 of anything in particular.
