How big is a 1/21 scale F-150 in length, In inches?

Answer 1

Go to Ford's web site and look up the overall length of the truck you are looking at. It could be a regular cab, or an extended cab, or a crew cab. Plus the bed lengths are different. You could have a 8ft,6.5ft, 5.5ft bed. Once you have the figure then just divide the total length by 21 and then the model should be that length. Most likely, somewhere around a foot in length. good luck.

Answer 2

full scale it is 211.2 inches so 1/21 would be just over 10 inches
