Add multiple windows by dimension to calculate total blinds needed
Add windows to see summary
Our blinds calculator helps you determine the total number of blinds needed for your home by adding multiple windows with their specific dimensions. Whether you're ordering custom blinds for a whole house or replacing window treatments in a few rooms, this tool organizes your measurements and calculates total costs.
Custom blinds are ordered based on exact window measurements, so accurate sizing is critical. The calculator groups windows by size so you can easily see how many blinds of each dimension you need. This is especially helpful when ordering from manufacturers who may offer quantity discounts.
This tool is perfect for homeowners planning a window treatment upgrade, interior designers specifying blinds for clients, and anyone asking "how many blinds do I need for my house?" The calculator also provides a materials estimate including mounting hardware.
