1. What is Drawer Box Height?

The drawer box height is the internal vertical dimension of a drawer after accounting for the bottom panel thickness. This measurement is crucial for proper drawer construction and functionality.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Drawer Height — Total external height of the drawer (mm)
• Bottom Thickness — Thickness of the drawer bottom panel (mm)

Explanation: The formula subtracts the bottom panel thickness from the total drawer height to determine the internal box height.

3. Importance of Accurate Measurements

Details: Precise drawer box dimensions ensure proper fit within cabinet openings, smooth operation, and correct clearances for drawer slides.

4. Using the Calculator

Tips: Enter drawer height and bottom thickness in millimeters. Both values must be positive numbers, with bottom thickness not exceeding drawer height.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical bottom thickness for drawers?
A: Common thicknesses range from 3mm to 12mm depending on material (plywood, MDF, solid wood).

Q2: Should I account for drawer slides in this calculation?
A: No, this calculates internal box height only. Slide clearance should be considered separately in your cabinet design.

Q3: What if my drawer has a lipped front?
A: The drawer height measurement should be to the back of the lip (total carcass height).

Q4: How precise do these measurements need to be?
A: For quality cabinetry, measurements should be accurate to within 0.5mm.

Q5: Does this work for inset drawers?
A: Yes, but you'll need to account for the reveal/gap around the drawer front in your cabinet opening dimensions.
