The stuff at the depot is a durable product and you could get it cut while you are there. Cut to the widest and trim to fit when you get home. It's available in 2' x 4' and 4' x 8'.
That's my 2¢.
Speaking of 2¢: Here's a random hint:
The big box hardware stores often have damaged pieces of Masonite (usually crushed corners) that they can't sell. Ask them about it, they will often sell them very cheaply.
