Opening-to-parts calculator

Drawer Box Cut List Calculator

Start with the measured cabinet opening and the exact clearance required by the selected slides. The result separates box stock from bottom-panel stock and creates a layout for each thickness.

Planning estimate: This model uses butt-jointed fronts and backs between full-length sides with an applied bottom. Captured bottoms, dovetails, lock-rabbets, undermount notches, and drilling patterns change the required dimensions.

Visible arithmetic

box width = opening width − total slide clearance

This model uses butt-jointed fronts and backs between full-length sides with an applied bottom. Captured bottoms, dovetails, lock-rabbets, undermount notches, and drilling patterns change the required dimensions.

Use the generated rectangles as a transparent starting point. The layout does not replace a construction drawing, hardware specification, load calculation, or safe cutting procedure.

Before material purchase

Checks the calculator cannot make from dimensions alone

Use the slide manufacturer's total side and rear clearances.
Confirm whether the bottom is applied or captured in grooves.
Cut one test box before batching the full quantity.
Keep bottom-panel stock separate when its thickness differs.
