Step-by-Step Measuring Process
Phase 1: Width Measurements
For optimal blackout curtain performance, measure width at three critical points:
| Measurement Point | Purpose | Add for Coverage | Notes |
|---|---|---|---|
| Top of Frame | Header area measurement | 6-12 inches each side | Most critical for light blocking |
| Middle of Frame | Check for bow or irregularities | Match top measurement | Use widest measurement |
| Bottom of Frame | Ensure consistent coverage | Match top measurement | Important for floor-length curtains |
Phase 2: Length Measurements
Length determines both style and functionality of your custom length blackout curtains:
Professional Length Options:
| Style | Measurement Method | Best Applications | Light Blocking Rating |
|---|---|---|---|
| Sill Length | Rod to sill minus 1/2 inch | Kitchen, bathroom, casual spaces | Good (85-90%) |
| Apron Length | Rod to 4-6 inches below sill | Traditional living rooms | Very Good (90-95%) |
| Floor Length (Float) | Rod to floor minus 1/2 inch | Bedrooms, formal dining | Excellent (95-98%) |
| Floor Length (Kiss) | Rod to floor exactly | Modern, contemporary spaces | Excellent (95-98%) |
| Puddle Length | Rod to floor plus 2-8 inches | Luxury, formal settings | Superior (98-100%) |
