I’ve been working on banner ads for a client for several weeks now and found the following modification to Photoshop CS2 to be a HUGE timesaver. You can use this tip to create any sort of page size defaults, if you wish!Obviously, this tip is for the Windows version of Photoshop…
- Go to: C:\Program Files\Adobe\Adobe Photoshop CS2\Required
- Open: Default New Doc Sizes.txt
- Add the following somewhere in the file:
; Standard IAB web banner sizes"Button 1" 120 90 pixels screen dpi RGB 8 1.0"Button 2" 120 60 pixels screen dpi RGB 8 1.0"Full Banner" 468 68 pixels screen dpi RGB 8 1.0"Half Banner" 234 60 pixels screen dpi RGB 8 1.0"Half Page Ad" 300 600 pixels screen dpi RGB 8 1.0"Large Rectangle" 336 280 pixels screen dpi RGB 8 1.0"Leaderboard" 728 90 pixels screen dpi RGB 8 1.0"Medium Rectangle" 300 250 pixels screen dpi RGB 8 1.0"Micro Bar" 88 31 pixels screen dpi RGB 8 1.0"Rectangle" 180 150 pixels screen dpi RGB 8 1.0"Skyscraper" 120 600 pixels screen dpi RGB 8 1.0"Square Button" 125 125 pixels screen dpi RGB 8 1.0"Square Pop-Up" 250 250 pixels screen dpi RGB 8 1.0"Vertical Banner" 120 240 pixels screen dpi RGB 8 1.0"Vertical Rectangle" 240 400 pixels screen dpi RGB 8 1.0"Wide Skyscraper" 160 600 pixels screen dpi RGB 8 1.0"separator"
- Restart Photoshop CS2.
Now, when you want to create a new document, you’ll have all of the IAB standard sizes at your disposal.

You can replace those entries with this to get all of the default IAB ad sizes into Photoshop CS3:
You can also do this in CS3. A few IAB ad sizes are actually included by default:
