How to Measure for Custom Casement Windows
When ordering custom casement windows China, accurate measurements are critical:
For New Construction:
1. Check architectural drawings for rough opening sizes
2. Subtract 20-30mm from width and height for installation gap
3. Example: 1500mm rough opening → order 1470mm window
4. Confirm measurements with builder before ordering
For Replacement Windows:
1. Measure existing window frame (width × height) at three points
2. Use smallest measurement to ensure fit
3. Check if frame is square (diagonal measurements should match)
4. Note any irregularities (out-of-square, bowing)
Measurement Tips:
- Always measure in millimeters for precision
- Measure width at top, middle, and bottom – use smallest
- Measure height at left, center, and right – use smallest
- Note opening direction (left-hand vs right-hand)
- Specify inward or outward opening
