Bedframe riser: The hole is 1.5" x 0.9" (38.1mm x 22.86mm) and goes 1" (25.4mm) deep. The riser will add 1" to the height of your bed frame.
Roundsingle: The hole is 1.1" (27.94mm) and goes 1" deep. The riser will add 1" to the height of your bed frame.
longriser: The hole is 2.35"x1.1" (59.69mm x 27.94mm) and goes 1" deep. The riser will add 1" to the height of your bed frame.
Of course you could always play with the scaling to change them. I designed them around one of the generic folding bed frames on amazon.
