Will it fit?

A TV, a couch, a cabinet, a sign: enter the wall width and the object width and see it to scale.

Yes. Centered, it leaves 2 ft 3.5 in open on each side.

How much do I need?

Works for paint, tile, flooring or anything sold by coverage. Enter the coverage printed on your product's label; every product is different, so we never guess it for you.

You need about 4 gallons, boxes or bags. Most people get one spare for touch-ups. This is an estimate; the real amount depends on the surface and how it is applied.
