is an option for Grid, Column and related constructs that specifies the sizes to allow for items.
  • Typical basic settings include:
Automaticseparately size items to fit within the total formatting width
Allmake all items the same width and height
Fullallow every item its full width and height
wgive all items width w
Scaled[s]give all items a fraction s of the total formatting width
{w,h}make all items the specified width and height
  • In Grid, w is measured in ems, and h in line heights. In GraphicsGrid, w and h are both measured in absolute printer's points.
  • The settings for ItemSize can be given as follows to apply separately to different items:
specapply spec to all items
{specx}apply specx at successive horizontal positions
{specx,specy}apply speck at successive horizontal and vertical positions
  • The speck can have the following forms:
{s1,s2,...,sn}use s1 through sn; then use defaults
{{c}}use c in all cases
{{c1,c2}}alternate between c1 and c2
{{c1,c2,...}}cycle through all ci
{s,{c}}use s, then repeatedly use c
{s1,{c},sn}use s1, then repeatedly use c, but use sn at the end
use the first sequence of si at the beginning, then cyclically use the ci, then use the last sequence of si at the end
{s1,s2,...,{},sm,...,sn}use the first sequence of si at the beginning and the last sequence at the end
{i1->v1,i2->v2,...}specify what to use at positions ik
{spec,rules}use rules to override specifications in spec
