# Spacing

Use this dialog to determine the spacing between formula elements. The spacing is specified as a percentage in relation to the base size defined under Format - Font Size.

Use the \<emph\>Category\</emph\> button to determine the formula element for which you would like to specify the spacing. The appearance of the dialog depends on the selected category. A preview window shows you which spacing is modified through the respective boxes.

## Category

This button allows you to select the category for which you would like to change the spacing.

## Spacing

Defines the spacing between variables and operators, between lines, and between root signs and radicals.

### Spacing

Defines the spacing between variables and operators.

### Line Spacing

Determines the spacing between lines.

### Root Spacing

Determines the spacing between the root sign and radicals.

## Indexes

Defines the spacing for superscript and subscript indexes.

### Superscript

Determines the spacing for superscript indexes.

### Subscript

Determines the spacing for subscript indexes.

## Fractions

Defines the spacing between the fraction bar and the numerator or denominator.

### Numerator

Determines the spacing between the fraction bar and the numerator.

### Denominator

Determines the spacing between the fraction bar and the denominator.

## Fraction Bars

Defines the excess length and line weight of the fraction bar.

### Excess length

Determines the excess length of the fraction line.

### Weight

Determines the weight of the fraction line.

## Limits

Defines the spacing between the sum symbol and the limit conditions.

### Upper limit

Determines the spacing between the sum symbol and the upper limit.

### Lower limit

Determines the spacing between the sum symbol and the lower limit.

## Brackets

Defines the spacing between brackets and the content.

### Excess size (left/right)

Determines the vertical distance between the upper edge of the contents and the upper end of the brackets.

### Spacing

Determines the horizontal distance between the contents and the upper end of the brackets.

### Scale all brackets

Scales all types of brackets. If you then enter ( a over b) in the Commands window, the brackets will surround the whole height of the argument. You normally achieve this effect by entering left ( a over b right ).

### Excess size

Adjusts the percentage excess size. At 0 percent the brackets are set so that they surround the argument at the same height. The higher the entered value is, the larger the vertical gap between the contents of the brackets and the external border of the brackets. The field can only be used in combination with Scale all brackets.

## Matrices

Defines the relative spacing for the elements in a matrix.

### Line spacing

Determines the spacing between matrix elements in a row.

### Column spacing

Determines the spacing between matrix elements in a column.

## Symbols

Defines the spacing of symbols in relation to variables

### Primary height

Defines the height of the symbols in relation to the baseline.

### Minimum spacing

Determines the minimum distance between a symbol and variable.

## Operators

Defines the spacing between operators and variables or numbers.

### Excess size

Determines the height from the variable to the operator's upper edge.

### Spacing

Determines the horizontal distance between operators and variables.

## Borders

Adds a border to your formula. This option is particularly useful if you want to integrate the formula into a text file in LibreOffice Writer. When making settings, be sure that you do not use 0 as a size, since this creates viewing problems for text that surrounds the insertion point.

### Left

The left border is positioned between the formula and background.

### Right

The right border is positioned between the formula and background.

### Top

The top border is positioned between the formula and background.

### Bottom

The bottom border is positioned between the formula and background.

## Default

Saves your changes as your default settings for all new formulas. A security response will appear before saving these changes.
