Window Blinds Calculator
Built for dealers that measure and install custom window treatments. The homeowner fills a card for every kind of window: roller, zebra, cellular or Roman shades, wood or vertical blinds, plantation shutters; width and height in inches, quantity, inside or outside mount and the room. Then what that treatment comes in: light-filtering, blackout or solar screen with its openness, single or double cell with top-down/bottom-up, 2 in or 2.5 in slats in faux or real wood, 2.5, 3.5 or 4.5 in louvers painted or stained, color families, cordless as the child-safe standard, cord loop or motorization by battery or hardwired, a valance. Prices are per square foot by treatment with a minimum billed area per window, percentage surcharges for fabric, cell, material and stain, options per window, installation per window, a trip charge waived above a threshold, quantity discounts from 5 and 10 windows, a promotion and a minimum order. The visitor chooses a free in-home measure and installation or shipping to the door, adds a smart-home hub when a shade is motorized, and gets a Letter-size PDF estimate with the window table.

Frequently Asked Questions
Can I set my own prices per square foot?
Yes. Every rate is a named constant at the top of the calculator: the price per square foot of each treatment, the minimum billed area per window, percentage surcharges for blackout, solar screen, double cell, real wood and stained shutters, per-window options like top-down/bottom-up, valance and motors, installation, the trip charge and its waiver threshold, quantity discounts and the minimum order.
Why is there a minimum billed area per window?
A small bathroom window takes as much work to make, measure and hang as a mid-size one, so the trade bills from a floor. The calculator uses 8 square feet by default: a 24 by 36 inch window is billed as 8 square feet, not 6. Set it to whatever your workroom uses.
How does the calculator handle several windows?
Windows with the same treatment, size and options are one card with a quantity, so a home with three identical bedroom windows is one card with quantity 3. Up to six different cards fit in one order, which covers a home where every room differs. The total count drives the 5-window and 10-window discounts.
Can customers order without an in-home measure?
Yes. The visitor chooses between your free in-home measure and installation or shipping to their door to the sizes they entered. The ship-to-me option drops the installation and trip charge and shows a warning that custom shades cannot be returned for a wrong measurement.
Will this work on my existing website?
Yes. Once you customize the calculator, you can embed it on any website - WordPress, Wix, Squarespace, or custom HTML. It is responsive and works on all devices, and the visitor can download a PDF estimate with the window table.
