## NAME

TTF\_FontIsFixedWidth - Query whether a font is fixed-width.

## HEADER FILE

Defined in SDL3\_ttf/SDL\_ttf.h

## SYNOPSIS

```
#include "SDL3_ttf/SDL_ttf.h"
```

**bool TTF\_FontIsFixedWidth(const TTF\_Font \*font);**

## DESCRIPTION

A "fixed-width" font means all glyphs are the same width across; a lowercase 'i' will be the same size across as a capital 'W', for example. This is common for terminals and text editors, and other apps that treat text as a grid. Most other things (WYSIWYG word processors, web pages, etc) are more likely to not be fixed-width in most cases.

## FUNCTION PARAMETERS

- *font*

  the font to query.

## RETURN VALUE

Returns true if the font is fixed-width, false otherwise.

## THREAD SAFETY

It is safe to call this function from any thread.

## AVAILABILITY

This function is available since SDL\_ttf 3.0.0.
