It all depends on the size of the original vehicle!

If a car is 870" long the scale model will be 10" long!

The determining factor is the original length of the car that the model is from. the 1:87 and the 1:43 are fractional representation of the actual size. In other words a 1:43 is a model that is 1" long for every 43" of length from the actual vehicle. for example if a vehicle is 18 feel long, that is 216 inches, 1:43 scale would make that model a little over 5 inches long. Of course the other dimensions would also be affected.

Where c = actual length in feet

where y = actual length in inches

where x = scale size in inches

(C/12)/43=X

Y/43=X

you can do the same thing replacing the 43 with 87 to determine that scales final length
