Length checks for product descriptions, ad copy, social captions and email subject lines.
The everyday operating tools of a one-to-five-person business: shrink a product photo for the marketplace, generate a QR code for the storefront, check the exchange rate before quoting a customer, generate UUIDs for an import, summarize a competitor blog post, count the words on a product description. Cheap, fast, and your inventory photos never leave your device.
Whatever the platform allows and the buyer will actually read: lead with the benefit in the first line, then the specifications. The counter exists so you can hit the platform’s hard limit without guessing.
Most marketplaces, ad platforms and social networks count every character including spaces, which is why the count rises faster than you expect. The tool shows both characters and words so you can match whichever rule applies.
Short enough not to be truncated on a phone, which in practice means roughly 40-60 characters. Paste the candidate into the counter and check the number rather than trusting the preview.
