Blind Size Calculator
Calculate order width and height for inside mount or outside mount blinds. Use the result to compare shade sizes before checking a retailer's exact measuring instructions.
Frequently asked questions
What is the difference between inside and outside mount?
Inside mount fits inside the window opening. Outside mount covers the opening from the wall or trim around it.
Why does the inside mount result use a deduction?
Many blinds need a small deduction so the headrail and shade move freely inside the opening.
Can I use this for every blind brand?
Use it for planning only. Brands publish their own minimum depths, deductions, and rounding rules.
