When capital letters are the right choice
All caps is a tool for short text that has to stand out or be read without mistakes:
- Official forms. Passport, visa, customs and bank forms often ask for block capitals because handwritten or scanned capitals are easier to read.
- Labels and signs. Warnings such as "DO NOT STACK", button labels and shipping marks.
- Acronyms and codes. Booking references, postcodes, flight numbers and product codes are usually written in capitals.
- Headings in some designs. Short section titles or navigation items, often styled with extra letter spacing.
- Constants in code. Many programming languages write fixed values in capitals by convention.
For anything longer than a line or two, capitals slow readers down because words lose their distinctive shapes, and in emails and chat they come across as shouting. If you want a headline to look important without that effect, the title case converter is usually a better fit.
Things worth knowing about uppercase
Some letters behave differently when capitalised. The German ß becomes SS, which makes the word one character longer, so check it if you are working against a strict character limit. Turkish and Azerbaijani have a dotted and a dotless i, and the result follows your browser's language setting. Scripts with no capital letters, including Urdu, Arabic and Hindi, are left as they are, so mixed-language text is safe to paste.
