Using a large iMac or Studio Display well

A 24 or 27 inch screen is big enough to waste. Layouts that use the space without turning it into a pile, from two columns to three plus a stack.

Guide · Updated 13 October 2026

On a big screen, a maximised window is too wide to read comfortably, and a scatter of small windows is hard to keep track of.

Layouts that fit

  • Two columns, two thirds and a third. Main work and a side panel.
  • Three columns. Equal thirds for comparing or for reference heavy work.
  • Two columns plus a stack. Main work, then a column with chat over music, or mail over calendar.

Keep reading width sensible

Text is easiest to read at roughly 60 to 80 characters a line. On a 27 inch screen that is far less than full width, which is why columns beat maximised windows.

Doing it with ClutterFreeMac

Pick Screens with three windows per screen for equal thirds, or Free scrolling to set each width yourself with ⌃ ⌥ R. Stack small windows into one column with ⌃ ⌥ ]. Gap and edge spacing are adjustable in Settings, Layout, so columns do not feel crammed on a big display.

Questions

How should I arrange windows on a 27 inch Mac screen?

In two or three columns rather than one maximised window, so each stays a comfortable reading width.
