Drawer Slide Calculator
Calculate the correct drawer slide length and clearance for your cabinet or furniture project.
Drawer Slide Size
Drawer slides must be sized correctly for smooth operation and proper fit.
Key measurements:
Drawer Width = Cabinet Opening Width - (2 × Slide Clearance)
Slide Length = Cabinet Depth - 1 inch (2.5 cm) for face frame, or full depth for frameless
Standard slide clearances (per side):
| Slide Type | Clearance per Side |
|---|---|
| Side-mount ball bearing | 1/2 inch (13 mm) |
| Under-mount | 3/16 inch (5 mm) |
| Center-mount | 0 (single track) |
| Euro/epoxy | 1/2 inch (13 mm) |
Standard slide lengths: Available in 2-inch increments: 10, 12, 14, 16, 18, 20, 22, 24 inches (25, 30, 35, 40, 45, 50, 55, 60 cm)
Weight ratings:
- Light duty: 75 lbs (34 kg)
- Medium duty: 100 lbs (45 kg)
- Heavy duty: 150+ lbs (68+ kg)
Always choose the longest slide that fits — longer slides provide more support and smoother operation.
