how much upholstery do i need?

[gwb72tii]

i'm going to redo my non-sport interior
i have badly used sport seats to recover. the center sections (front and rear) will be plaid cloth and i want to do door cards to match (coupe).
anyone work thru this and know how much cloth is needed?

BTW - I'm ordering the cloth from Germany and will post up before i order if anyone wants to piggy back on my order.

TIA

Depends on the cuttable width but 10 linear yards will be more than enough to do all door cards, front seats and back seats.
