Custom Window Size and Position in Rectangle Pro for Mac

By Joel Dare - Updated September 9, 2025 - Written April 22, 2023

I use the Rectangle Pro app to organize windows on my Mac. Most of the time, the default sizes and positions work great. There’s one case where I need a custom position and size - I like to record 1080p video screen captures.

Here’s how you make a custom window size and position in Rectangle Pro. Note that this option doesn’t exist in the free version of Rectangle–it’s a pro feature.

Select the Rectangle icon in the Menu Bar, then select Settings
Select Custom Size and Position on the left
Click the plus button then New Size/Position
Specify the Name, Position, Size and other parameters
Click Record Shortcut to assign a keyboard shortcut
Click Done and close the window

Now press your keyboard combination to resize the current window.
