If using 1 layer of 3/4" MDF, subtract 1.5" from each axis (3/4" for each side wall) to get net internal dimensions. Make sense?

Subtract 1.5 from external W to get internal, subtract 1.5 from external D to get internal, and subtract 1.5 from external H to get internal.
That is assuming 3/4" MDF.
It really isn't that hard to do the math.
.75+.75=1.5
Kinda like 1+1=2
