That's completely normal, you'll need to trim it to the desired width. If a hole is needing to be cut for seats, console, etc, it is always best to start with a small slice as a test fit.
Slices can be easily taped back together if they are in the wrong spot, holes cannot. Never use the old carpet as a template for the new one. It is fine to reference it, but it should not be your guide for cutting. Online carpet color samples will give the general idea of the color of the carpet.
However, all computer monitors are different, which means the color may or may not be a match for your specific vehicle. Please make sure the carpet fits the floorpan before making any cuts or alterations. Once cut, glued, or altered, the carpet is no longer returnable.This carpet is designed to match carpets used in most domestic vehicles manufactured before 1974.
