Buy the right ready-made curtains. First time.
CurtainFit walks you through your house room by room, helps you measure every window, and tells you exactly which ready-made curtain size to pick up at the shop. No guessing, no second trip to return the wrong ones.
Start measuring — it's freeWorks in your phone's browser. Nothing to download.

How it works
Three steps, one shopping list
Walk and label
Start at the kitchen sink and walk the house. Tap to add each room and number its windows and doors. No tape measure yet.
Measure each window
The app shows you exactly where to put the tape, in millimetres, one window at a time. Picture guides show what each number means.
Take your list to the shop
Get a shopping list with the curtain width and drop each window needs. Match the numbers to the label on the box, with any brand.
Why CurtainFit
Ready-made curtains are cheap. Getting the size wrong isn't.
- Sizes that actually fit. CurtainFit checks the curtains will be full enough to look good, and tells you when you need the bigger size or two packs.
- The right drop. It finds the length that just clears the floor, and tells you when no standard size will do.
- Any shop, any brand. You get plain sizes, not product codes, so you can buy wherever you like.
- No wasted packs. A pack has two panels. If a window only needs one, the app remembers the spare for another window.
- The whole house in one go. Every room is labelled, so the list matches the windows when you get home.
Questions
Good to know
Does it cost anything?
Not while CurtainFit is in beta. Paid plans for bigger jobs will come later, and you'll always be able to try it free first.
Do I need to download an app?
No. It runs in your phone's browser. If you like, use "Add to Home screen" from the browser menu so it opens like any other app.
What if I lose signal halfway through?
Keep going. Your rooms and measurements are saved on your phone as you type. You just need to be online to work out the final sizes and make your shopping list.
Does it work for blinds or made-to-measure curtains?
CurtainFit works out sizes for ready-made curtains. For other window coverings it records your measurements neatly, so you can hand them to a professional.
Which measurements does it use?
Millimetres, the same as the sizes printed on New Zealand curtain packs.
