How to Measure Your Door
Accurate measurements are critical for selecting compatible locks. Use this guide to measure your doors correctly:
Door Specification Requirements
| Specification | Minimum | Recommended | Maximum | Notes |
|---|---|---|---|---|
| Door Thickness | 35mm | 40-45mm | 60mm | Most smart locks designed for 40-45mm |
| Door Width | 800mm | 900-950mm | 1200mm | Standard hotel room door is 900mm |
| Door Height | 2000mm | 2100mm | 2400mm | Fire-rated doors often taller |
| Backset (Lock to Edge) | 60mm | 60-70mm | 100mm | Common: 60mm (US) or 70mm (EU) |
| Bore Hole Diameter | 54mm | 54-60mm | 70mm | Cylindrical: 54mm, Mortise: varies |
| ⚠️ Hollow Core Doors | NOT RECOMMENDED | Insufficient strength for smart locks | ||
- Solid core construction - Supports lock weight (2-4kg)
- Standard thickness - 40-45mm fits all locks
- Stable frame - No warping or sagging
- Smooth operation - Properly aligned hinges
- Fire-rated certified - If required by code
- Hollow core doors - Can't support lock weight
- Non-standard thickness - Requires custom spacers
- Glass doors without frame - Need specialized locks
- Warped doors - Lock may not align/latch
- Old/damaged frames - May need reinforcement
Before ordering locks: Measure 5-10 sample doors across your property. Door thickness can vary by ±2mm even in same building. Check for: warping (door doesn't close flush), frame damage, existing hole alignment, and fire-rating labels.
Professional tip: Order 2-3 extra locks for testing. Install on problem doors first to identify issues before bulk installation.
