Warning! Facebook Page Custom Tabs Will Shrink to 520 Pixels by End of August

Facebook has now warned that the change in width of custom tabs for Facebook Pages will happen this month.

Currently a custom tab has 720 pixels of width to play with but by the end of August 2010 it will go down to 520 pixels.

Some say it is to allow for mobile devices to view Pages more efficiently – others say it will allow Facebook to use larger ad formats.

So if you are a Page admin I suggest you look at the content of your custom tabs and change what you need so that when the tab shrinks to 520 pixels things still work.
