Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

Let(
[
 L = Length ( Text );
 Bracket = increment/(Idealsize-increment); 
 

Nothing=0];

If (L<=CharSpace;
TextSize(text;IdealSize);
SizeMask (text ; idealsize-Increment; Increment; CharSpace+(CharSpace*Bracket))

) // end if



)  // end let

Useful particularly for form outputs where you want text to conform to certain width without breaking to a new line. Notes:

IdealSize - should be specified in the font point size you want most masked items to appear.

Increment - specify how much to shrink the font by when text runs over the specified width. A lower "Increment" will trigger more drops in font size, but makes optimum use of space and the drops will be less radical.

CharSpace - specifies the width you are trying to constrain to, expressed in number of characters.
