1. What is the UK Blind Size Calculation?

The standard UK practice for measuring blinds is to subtract 1 cm from the window recess measurement. This ensures the blind fits properly within the recess without being too tight.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Window Recess — The measured width of your window recess in centimeters
• 1 cm — The standard deduction for UK blind fittings

3. Importance of Accurate Blind Sizing

Details: Proper blind sizing ensures smooth operation, complete coverage, and a professional appearance. Too large blinds won't fit, while too small ones may look undersized.

4. Using the Calculator

Tips: Measure your window recess width accurately in centimeters. Enter this measurement to calculate the appropriate blind size (1 cm less than recess).

5. Frequently Asked Questions (FAQ)

Q1: Why subtract 1 cm for UK blinds?
A: This standard deduction accounts for fitting brackets and ensures the blind operates smoothly within the recess.

Q2: Is this the same for all blind types?
A: Most recess-fit blinds follow this rule, but some specialized blinds may have different requirements - always check manufacturer guidelines.

Q3: How should I measure my window recess?
A: Measure the width at the top, middle, and bottom of the recess, using the smallest measurement as your base.

Q4: What about very large windows?
A: For windows wider than 200 cm, consult with your blind supplier as additional deductions may be needed.

Q5: Can I use this for outside-mounted blinds?
A: No, this calculator is specifically for UK-style recess-fit blinds. Outside mounts require different calculations.
