Both calculators run independently β change the inputs on either side to compare results.
Plywood Sheet Optimization Calculator
Calculates the minimum number of full plywood sheets needed to yield a required number of identical rectangular pieces, accounting for saw kerf loss. Use it before ordering materials to avoid costly over-buying.
Wood Screw Pilot Hole Calculator
Determines the correct pilot hole diameter for wood screws based on screw size, wood hardness, head type, and thread pattern. Use it to prevent splitting and ensure full thread engagement in any wood species.
Pilot Hole Diameter
0.14 inches
About 1/8"-5/32" is typical for #8-#10 screws; the 0.14" example sits here. Drilling deeper than the screw length prevents the tip binding in hardwood.
Pilot diameter scales with screw gauge; woodworking guides recommend pilots roughly 70-90% of the screw's root diameter, from about 5/64" for a #6 to 11/64" for a #14.
