can you cut drywall? , I do not need exact measurements, just to be able to take it

Idk if they do

Home Depot sells 4 ft X 8 ft sheets. Watch a YouTube video on cutting it. Take a helper and cut it in the parking lot.

Yes, razor knifes work best.

Yes... When you buy it from the store. It's about 14x5ft. Be careful, It breaks easily.

After you buy it home depot doesn't care If you cut it
