Size Marks is a helpful Photoshop script for web designers and front-end engineers.

Script converts rectangular marquee to labeled measurement mark. Landscape marquee → horizontal mark. Portrait or square marquee → vertical mark.

1. Right click: Size-Marks.jsx-v0.1.1.zip and choose Download Linked File As....
2. Unzip and place Size Marks.jsx in the Photoshop’s Scripts folder. For OS X: /Applications/Adobe Photoshop CC 2014/Presets/Scripts/ and restart Photoshop.
3. Now script is available in File ▸ Scripts ▸ Size Marks. Let’s make a shortcut.
4. Edit ▸ Keyboard Shortcuts.... Unwrap File and scroll to Scripts>. Select Size Marks and set shortcut. I recommend Shift+Cmd+P (⇧⌘P) — it must be available.

Create rectangular selection with Rectangular Marquee Tool (M) and use your shortcut (see Install section).

Script has been tested for Photoshop CC 2014 on OS X Yosemite. If you have troubles, drop me a line: @romanshamin.
