# glossaries package FAQ

I’ve used the `smallcaps` option, but the acronyms are displayed in normal sized upper case letters. 🔗

The `smallcaps` package option (or the `sc` acronym styles, such as `long-sc-short`) uses `\textsc` to typeset the acronyms. This command converts lower case letters to small capitals, while upper case letters remain their usual size. Therefore you need to specify the acronym in lower case letters.

If you prefer to keep upper case letters in your entry definitions, you could redefine `\acronymfont` so that it converts the letters to lower case. For example:

```\renewcommand{\acronymfont}[1]{\textsc{\MakeLowercase{#1}}}
```

Alternatively, consider using the “smaller” (`sm`) styles instead.

Note that if you are using glossaries-extra, the `\acronymfont` command isn’t used by the abbreviation styles. In this case, the `sc` styles use `\glsxtrscfont`, so that’s the command that will need changing. Note that if you are using bib2gls, you can instruct bib2gls to perform the case-conversion instead (see the `short-case-change` resource option).
