How Much Paint For Interior?

[Machspeed]

I need to order some paint for the interior of my 69 Fastback and looking for an approximate quantity. This is strictly for the interior cab and trunk area. I've read 3 oz per panel per coat. Can I get some idea as to what you guys think the actual amount of sprayable paint will be?

If it were me I'd get a quart if doing entire trunk floor, trunk sides, etc . Even a 1:1 mix ratio would be cutting it short if a pint is purchased.
