To measure the height of a drawer box, you typically measure the cabinet opening height and subtract a specific clearance.
Measuring the correct height for a drawer box ensures it fits properly within the cabinet opening and operates smoothly. This measurement isn't simply the internal height of the opening; it involves accounting for necessary clearance at the top and bottom.
Measuring Steps for Drawer Box Height
Based on common practices and the provided reference, here is the process to determine the appropriate height for your drawer box:
- Measure the Cabinet Opening Height: Carefully measure the inside vertical distance of the cabinet opening, from the bottom frame or surface up to the top frame or surface. Measure from frame to frame (inside).
- Subtract for Clearance: To allow for smooth operation and account for potential variations or hardware, you must subtract at least 1/2 inch from this measured opening height. This crucial step provides necessary clearance.
- Determine Available Drawer Box Height: Drawer box heights are often manufactured in specific increments, such as 1/2-inch increments.
- Round Down to the Nearest Increment: After subtracting the clearance, round the resulting measurement down to the nearest available drawer box height offered by your supplier.
Example Calculation
Let's use the example provided in the reference:
- Cabinet Opening Height: 4 3/4 inches
- Subtract Clearance (at least 1/2"): 4 3/4" - 1/2" = 4 1/4 inches
- Available Drawer Box Increments: 1/2 inch
- Round Down: Since drawer heights are offered in 1/2" increments (e.g., 3", 3.5", 4", 4.5", etc.), you must round the 4 1/4" down to the nearest smaller available height.
- Recommended Drawer Box Height: 4 inches
| Step | Measurement/Action | Result |
|---|---|---|
| 1. Cabinet Opening Height | Measure frame to frame | 4 3/4" |
| 2. Subtract Clearance (min 1/2") | 4 3/4" - 1/2" | 4 1/4" |
| 3. Available Increments | (Example: 1/2" steps) | - |
| 4. Round Down | To nearest available size | 4" |
Note: Always confirm the minimum required clearance and the available height increments with your specific drawer box supplier.
Following these steps ensures your new drawer box fits correctly within your cabinet space, allowing for the necessary clearance for drawer slides and preventing binding.
