## Base size

All elements of a formula are proportionally scaled to the base size. To change the base size, select or type in the desired point (pt) size. You can also use other units of measure or other metrics, which are then automatically converted to points.

To permanently change the default size (12 pt) used in LibreOffice Math, you must first set the size (for example, 11 pt) and then click the Default button.

## Relative Sizes

In this section, you can determine the relative sizes for each type of element with reference to the base size.

### Text

Select the size for text in a formula relative to the base size.

### Indices

Select the relative size for the indices in a formula in proportion to the base size.

### Functions

Select the relative size for names and other function elements in a formula in proportion to the base size.

### Operators

Select the relative size of the mathematical operators in a formula in proportion to the base size.

### Limits

Select the relative size for the limits in a formula in proportion to the base size.
