# TTF_GetStringSize

Calculate the dimensions of a rendered string of UTF-8 text.

## Header File

Defined in [<SDL3_ttf/SDL_ttf.h>](https://github.com/libsdl-org/SDL_ttf/blob/main/include/SDL3_ttf/SDL_ttf.h)

## Syntax

```c
bool TTF_GetStringSize(TTF_Font *font, const char *text, size_t length, int *w, int *h);
```

## Function Parameters

|                        |            |                                                                  |
| ---------------------- | ---------- | ---------------------------------------------------------------- |
| [TTF_Font](TTF_Font) * | **font**   | the font to query.                                               |
| const char *           | **text**   | text to calculate, in UTF-8 encoding.                            |
| size_t                 | **length** | the length of the text, in bytes, or 0 for null terminated text. |
| int *                  | **w**      | will be filled with width, in pixels, on return.                 |
| int *                  | **h**      | will be filled with height, in pixels, on return.                |

## Return Value

(bool) Returns true on success or false on failure; call SDL_GetError() for
more information.

## Remarks

This will report the width and height, in pixels, of the space that the
specified string will take to fully render.

## Thread Safety

This function should be called on the thread that created the font.

## Version

This function is available since SDL_ttf 3.0.0.
