The Size field is a drop-down combination box that displays available font sizes. Users can display and select from a list of available sizes for a font, or they can type a font size directly into the entry field.

When users select a font size from the drop-down list, the Size field display is refreshed with the selected size. The preview area is updated to show the character string in the selected font size, using the family name, font style, and emphasis currently in effect.

The font sizes included in the drop-down list are dependent on the character definition of the font. For image or raster fonts, all available sizes are listed. For outline fonts, the default sizes are 8, 10, 12, 14, 18, and 24 points. If required, the application can specify the available sizes for outline fonts.

When users type a font size in the entry field, the preview area is updated immediately. The Size field will accept a fixed point number, such as 24.25, with up to four places saved after the decimal.
