Measure once, choose right, order with confidence.
Window Treatment Tools & Calculators
Free tools for every window — blind & shade size calculator, curtain fabric calculator, treatment cost estimator, light-blocking opacity selector, slat count calculator, and a cord safety check.
Blind & Shade Size Calculator
Turn a measured opening into the size to order — inside or outside mount, with the clearance or overlap already applied, in inches or centimetres.
Curtain Fabric Calculator
Work out how much fabric to buy from your track width, drop, fullness, and pattern repeat — the number of drops and the total yardage or metres.
Window Treatment Cost Estimator
Budget a whole home by window count — list your windows and prices, add fitting, fees, a discount, and tax, and see the total and cost per window.
Light-Blocking Opacity Selector
Match a room to the right opacity — sheer, light-filtering, room-darkening, or blackout — with its light-blocking range and privacy.
Slat Count & Ladder Spacing Calculator
Estimate the slats in a venetian or faux-wood blind and the ladder pitch from the drop and slat width, plus the raised stack height.
Blind Cord Safety Calculator
Check whether a cord or chain is within a child's reach, find the longest safe length, and see when a cordless blind is the safer choice.
Museum of Windows & Décor
Wander an immersive, richly illustrated collection — the long history of blinds and shutters, the textiles and drapery that dress a room, the interior-design movements that shaped how we treat windows, and the architecture that framed them, each in its own gallery. Every entry, image, and fact is drawn from Wikipedia and Wikimedia Commons.
