In the garage at our old house, I lined one wall with white pegboard for the wife's gardening tools. Brightened the garage quite a bit.
This was maybe 10 years ago (maybe more).
Anyhow, it turns out the pegboard was 4' plus a little extra (1/8 or maybe 1/16th). By the time I got to the end of the wall, i couldn't keep the edge on the stud. I thought it was the studs, but it turns out the pegboard was slightly oversize.
I don't know if it's still that way. It would have been (relatively) easy to trim it on the tablesaw if I had realized prior to putting it up.
