Contact Blindset

Blindset is a small, independent, ad-supported site — there is no support desk standing by, but a real person reads everything that comes in to support@blindset.com.

A few things this address is genuinely useful for: a calculator that gave you a result you think is wrong (say which tool — the blind & shade size calculator, curtain fabric calculator, window treatment cost estimator, light-blocking opacity selector, slat count calculator, or blind cord safety calculator — and the values you entered); a tool you wish existed on the site; an error or unclear step in the blog, learn section, or the museum; or a bug in how a page looks or behaves on your device.

There’s no fixed response time to promise, and no ticket number or live chat — email is read and handled as it comes in. If your question is really “which blind should I buy for this exact window?”, a local blinds fitter or the retailer’s own measuring service will serve you far better than this site can: Blindset provides general-purpose calculators and explanations, not a made-to-measure quoting or fitting service, and it isn’t affiliated with any manufacturer or retailer.

Before writing in about a tool result, it’s worth double-checking the numbers you entered — the wrong units (inches versus centimetres), a mount type that doesn’t match your window, or a mistyped measurement is the most common source of a surprising answer. If it still looks off after that, that’s exactly the kind of message worth sending.
