upholstery help needed

I have found some upholstery I would like to try and redo my truck seat in but before I purchase it I need to know how much to get. I would just go out and measure the seat but I don't have access to it.

Full bench seat in a 1949 F-1 Pickup.

Material for the top yards?
Material for the Bottom yards?

Any help would be greatly appreciated.

 

The best way is to measure the actual seat. There will be a bunch of small pieces that you'll need to pattern . Remember to keep the nap running in the correct direction on both bottom and back or you'll get a mismatched color, or will appear to be mismatched.

 

Total of 54'' wide material, 2 1/2 yards.
