How to Measure Your Windows for Custom Blinds: A Step‑by‑Step NZ Homeowner’s Guide
Practical, photo‑friendly steps for measuring inside and outside mounts, tricky frames, ranch sliders and skylights so you can order custom blinds online with confidence from Easy Blinds Auckland.
Why getting measurements right matters
A correct measure is the difference between a neat, professionally fitted blind and an expensive refit. For custom blinds — whether roller, venetian, honeycomb or motorised — the fitter uses the measurements you supply to make the product to size. Many Easy Blinds customers report that clear measuring guidance makes ordering online straightforward, and some have had the team step in to help when measurements needed adjustment.
Tools to have on hand
Use a reliable metal tape measure, a pencil or removable marker, a step ladder for high windows, and a notebook or phone to label each measurement. Measure in millimetres (mm) where possible for best accuracy. If you can, take clear photos of the window from both inside and outside and include any nearby obstructions such as handles, rails or architraves.
Inside‑mount windows: step‑by‑step
Inside‑mounts sit within the window recess. Measure the width at three points — top, middle and bottom — and record the smallest of the three so the blind will fit into the tightest spot. Measure the drop (height) from the top of the recess to the sill at three points and record the longest measurement so the blind will cover the full opening. Note the exact depth of the recess if a cassette or headrail needs to sit flush to the frame. Label each measurement clearly (e.g. ‘Lounge bay — width top/mid/bottom; drop’).
Outside‑mount windows: step‑by‑step
Outside‑mounts cover the face of the window or architrave. Measure the total width of the area you want covered — from outside edge to outside edge — and the drop from the top mounting point to where you want the blind to finish. Outside mounts give more tolerance for imperfect recesses and are often the best choice for slim or shallow frames. For privacy or light control, decide how much overlap you want beyond the glass and note that on your order so the maker can advise on sizing for your chosen blind style.
Tricky shapes: skylights, ranch sliders, bays and obstructions
Skylights and roof deck glazing usually require measuring between rafters or battens and checking available headroom for the blind stack — many customers have successfully fitted Duette/honeycomb skylight blinds with good guidance. For ranch sliders and sliding doors, measure the full width of the door frame and the track area; take note of where the blind will mount (inside the frame, face fixed to the wall, or to the ceiling). For bay windows, measure each panel separately and label them clearly. Always note obstructions (handles, catches, mouldings, security stays) and include photos so the manufacturer can flag any special hardware requirements.
Double‑check, photograph and use the support on offer

If something goes wrong — next steps and contact tips
If a blind doesn’t fit as expected, many customers report the Easy Blinds team is willing to work through corrections or adjustments. If you discover an issue after installation, take clear photos, note the original measurements you supplied, and contact the supplier with your order number. For first‑time DIY measurers, consider asking for advice when ordering — free quotes and samples make it easy to check before production.
