Questions people ask
How many characters can you use on Instagram, X and WhatsApp?
Type or paste your caption, bio or ad text and a table shows how it fits the commonly published limits for X, Instagram, WhatsApp, Meta ads, Google Ads and SMS. Trim until the places you need show Left. Platforms change limits, so leave a small margin, especially with emoji.

How do I check character limits for social media?
Type or paste your text into the box and look at the table. It shows the commonly published limits for X, Instagram, WhatsApp, Meta ads, Google Ads and SMS, and how many characters you have left for each. Trim the text until the places you need show Left.
Are these limits always right?
They're the limits commonly published for each place, and platforms change them from time to time. Always check the platform itself if a post must be exact. Meta ad lengths are recommendations for how much shows before truncation, not hard stops. Leave a little margin.
Do emoji count as one character?
Here, an emoji counts as one character. Some platforms count certain emoji as two or more, especially combined ones such as family or skin-tone emoji. Leave a small margin when your text is close to a limit and contains several emoji. Test long captions first.
Why does X count links differently?
X counts any link as 23 characters, whatever its actual length. This tool counts the characters you typed, so a post with a long link may fit on X even when it looks too long here. Shorter links don't save space on X. Plan around 23.
What about Hindi text?
Each Devanagari letter and sign counts as a character. SMS in Hindi, or any message with non-Latin characters, uses a shorter limit of 70 characters per message part instead of 160, so Hindi SMS campaigns split into parts sooner and can cost more. Plan Hindi SMS accordingly.
How long can an Instagram bio be?
Instagram bios have a short limit, published as 150 characters. The table shows how much room you have left. Use it for what you do, where you are and how to contact you, and put a booking or WhatsApp link in the link field. Short bios read better.
How long can a Google Ads headline be?
Responsive search ad headlines are limited to 30 characters each, and descriptions to 90. The table checks against these, so you can draft several headlines here before pasting them into Google Ads, where text over the limit can't be saved. Write several variations here. Short headlines often perform well.
How many characters fit in one SMS?
160 characters for plain English text in one SMS part, and 70 for Hindi or text with special characters. Longer messages are split into parts, each with a slightly smaller limit, and each part is usually billed separately by SMS providers. Shorter messages cost less to send.
Is my text uploaded?
No. Counting happens in your browser, so captions, ad copy and drafts stay on your device. Nothing is stored or shared, which is useful when preparing campaigns that haven't launched yet. Draft as many versions as you like without anything being saved, shared or kept on our side.
Does WhatsApp have a character limit?
WhatsApp messages can be very long, but WhatsApp Business template messages and profile fields have limits, such as the business description. The table shows the commonly published WhatsApp limits for the fields people usually ask about. The WhatsApp About field, for example, allows 139 characters.
Why does my text look shorter here than on the platform?
Platforms may count some characters differently, such as emoji, line breaks or links, and some add text such as your handle. The count here is the raw number of characters you typed. Leave a margin of a few characters to be safe. Preview before posting.
Do line breaks count as characters?
Yes, each line break counts as a character here, and most platforms count them too. Captions with many line breaks for spacing use up the limit faster than you might expect, so check the count after formatting your text. Each one also takes up space in previews.
Can I write ad copy here?
Yes. Many marketers draft headlines and descriptions here, checking each against the limits, then copy them into the ad platform. Keep a few variations, because platforms such as Google Ads test several headlines automatically. Meta's recommended lengths are shown too, marked as guides rather than hard limits.
Does it work on a phone?
Yes. Type or paste your caption on your phone and check the table before posting. It's quick for Instagram bios, WhatsApp Status text and ad copy written on the go. No app is needed, and nothing is uploaded. Counts update as you type. The table fits small screens too.
Is it free?
Yes. The character counter is free, with no sign-up and no limit. It sits with other free text tools from Marketiism, such as the word counter, fancy text generator and emoji picker, all running in your browser. Nothing is added to your text, there's no daily limit, and you can use it for business and client work.
