Window Measuring Guide

Step-by-step instructions to measure your windows in centimetres for a perfect-fit zebra blind.

Zebra Blinds — Custom Sizing Guide (cm)

Choose Your Mount Type

Before measuring, decide whether you want an inside mount (blind sits inside the window frame) or an outside mount (blind is mounted on the wall above and around the frame).

Inside Mount

The blind installs inside the window frame recess. Gives a clean, built-in look. Requires at least 2–3 inches of depth in the frame.

Outside Mount

The blind is mounted on the wall above the window frame. Blocks more light, makes windows appear larger, and works for any window depth.

Inside Mount — Step by Step

1

Measure the Width — 3 Places

Inside the window frame, use a digital laser measure to measure the width at the top, middle, and bottom. Use the narrowest measurement. This ensures the blind fits inside the frame without gaps.

Always use the smallest of the 3 width measurements.
2

Measure the Height — 3 Places

Use your digital laser tool to measure the height on the left side, center, and right side of the inside frame. Use the longest measurement so the blind covers the full opening.

Use the longest of the 3 height measurements.
3

Record to the Nearest Millimetre

Write down your measurements precisely in centimetres. Zebra blinds are custom-cut, so accuracy matters. Do NOT round up or down to the nearest centimetre.

Example: 87.5 cm W × 158.2 cm H

No Deductions Needed

For inside mount, submit your exact measurements in centimetres. Our factory applies the standard deduction automatically to ensure a smooth fit inside the frame.

We handle the deduction — you just provide the raw window opening size.

Measure width at top, middle & bottom (in cm) — use the narrowest. Measure height left, center & right — use the longest.

Pro Measuring Tips

📡

Use a digital laser measure for precise centimetre readings — far more accurate than tape measures.

✏️

Measure twice, order once. Double-check every measurement in centimetres before submitting.

🔍

Check for obstructions — handles, cranks, or locks inside the frame that could block the blind.

📏

For multiple windows, measure each one individually — even identical-looking windows can differ by centimetres.

☀️

For maximum light blockage, always choose outside mount with extra width overlap.

Rental properties? Outside mount leaves no permanent holes in the window frame.
