1. What is the Blum Drawer Box Calculator?

The Blum Drawer Box Calculator helps determine the correct drawer box width based on your cabinet dimensions when using Blum drawer slides. It accounts for the necessary clearance for smooth operation of the slides.

2. How Does the Calculator Work?

The calculator uses the Blum formula:

Where:

• \( Cabinet\ Width \) — The internal width of your cabinet (mm)
• \( 42mm \) — The required clearance for Blum slides (21mm per side)

Explanation: The 42mm deduction accounts for the space needed by the drawer slides on both sides of the cabinet.

3. Importance of Proper Drawer Box Sizing

Details: Correct drawer box sizing ensures smooth operation, proper alignment of drawer fronts, and prevents binding or misalignment of the drawer slides.

4. Using the Calculator

Tips: Measure the internal width of your cabinet precisely. For multiple drawers, the calculator will recommend front widths that allow for proper gaps between drawer fronts.

5. Frequently Asked Questions (FAQ)

Q1: Is the 42mm deduction always accurate?
A: This is the standard for Blum undermount slides. Always check specifications for your specific slide model.

Q2: How much gap should be between drawer fronts?
A: Typically 1-2mm between drawer fronts is recommended for a professional look.

Q3: Does this work for all Blum slides?
A: This works for most Blum undermount slides. Side-mount slides may have different requirements.

Q4: What about height calculations?
A: Drawer box height depends on your cabinet height and desired drawer configuration, not included in this calculator.

Q5: Should I account for cabinet material thickness?
A: No, use the internal cabinet width between the side panels.
