Measuring Sliding Doors for Blind Installation in Brisbane Homes

Inside Mount vs Outside Mount

Inside mount means the blind fits inside the door recess. The blind sits between the walls or ceiling. This creates a clean, built-in look. Inside mounting requires sufficient depth for the blind mechanism.

Outside mount means the blind covers the entire opening plus overlap. It mounts to the wall or ceiling outside the recess. This maximises light blocking and works when there is insufficient depth for inside mounting.

Most sliding door blinds use outside mounting. The wide opening and lack of deep recess make inside mounting impractical. Outside mounting also allows the blind to clear door handles and locks.

What You Need to Measure

Width is the most critical measurement. Measure the full width of the sliding door frame from outside edge to outside edge. Add overlap on each side to prevent light gaps. Typically add fifty to one hundred millimetres per side.

Height matters equally. Measure from where the blind will mount to where you want it to finish. Allow for the mounting bracket height. Measure at multiple points as floors and ceilings can be uneven.

Mounting clearance affects installation. Measure from the top of the door frame to the ceiling. There must be enough space for mounting brackets and the blind mechanism. Most systems need at least seventy-five millimetres clearance.

Handle and lock positions need noting. The blind must not interfere with door operation. Measure how far handles and locks project. Note which side the door slides to when open.

• Width: Full frame plus overlap
• Height: Mount point to finish point
• Clearance: Space above frame
• Obstructions: Handles, locks, tracks

Common Measuring Mistakes

Measuring to the wrong points is the most common error. Measure to the outside of the frame, not the glass. The frame adds width you must account for. Missing this results in blinds that do not cover fully.

Forgetting overlap creates light gaps. Outside mount blinds need overlap to block light at the edges. Without overlap, you get bright strips down each side. This defeats the purpose of the blind.

Not allowing for handle clearance causes operation problems. Blinds that hit door handles cannot lower fully. Or they prevent the door from opening. Always measure handle projection and position.

Assuming walls and ceilings are square leads to fitting issues. Brisbane homes, especially older ones, often have uneven walls and ceilings. Measure at multiple points and use the largest measurement.

Tools You Need

A steel measuring tape is essential. Fabric tapes stretch and give inaccurate measurements. Use a five-metre tape minimum for wide sliding doors. Lock the tape when taking measurements to prevent creep.

A level helps check if mounting surfaces are straight. This matters for track installation. Uneven mounting causes blinds to hang incorrectly or bind during operation.

A notepad records all measurements. Write down each measurement with labels. Take photos of the door from multiple angles. This information helps when ordering or discussing options.

Brisbane Home Specifics

Queenslander-style homes often have wide sliding doors opening to verandahs. These doors can be three to four metres wide. Measure carefully as any error is magnified across the width. Consider whether one wide blind or multiple blinds works better.

Older Brisbane homes may have unlevel floors and ceilings. The ceiling might slope or the floor may not be flat. Measure height at both ends and the middle. Use the shortest height to ensure the blind does not drag on the floor.

Modern apartments and townhouses usually have standard sliding door sizes. Measurements still matter as frames vary. The actual opening might be slightly different from standard even in new builds.

Multiple Blind Configurations

Very wide sliding doors sometimes need multiple blinds. Each blind operates independently. You need to measure each section and consider where blinds meet in the middle.

Overlapping blinds in the centre eliminates light gaps. The blinds overlap by at least twenty-five millimetres. This requires careful measuring and ordering. Professional measuring ensures correct overlap.

Stack position matters with multiple blinds. Note which direction each blind should stack to keep the opening clear. This affects how you position the controls and mounting brackets.

Common Questions

Should I measure in millimetres or centimetres?

Always use millimetres for blind measurements. Millimetres provide the precision needed. A few centimetres error on a wide sliding door creates visible gaps or fitting problems. Professional installers work in millimetres.

Can I measure sliding doors myself?

You can, but professional measuring is recommended. Sliding doors involve multiple measurements and considerations that are easy to miss. Professional measuring is usually free when you buy blinds and guarantees correct fit.

What if my measurements are different at each end?

Use the largest width measurement to ensure coverage. Use the shortest height measurement to prevent dragging. Professionals adjust for these variations during manufacture and installation.

When to Call a Professional

Sliding door blind measuring is more complex than regular windows. The width, mounting challenges, and door operation add multiple factors. Professional measuring ensures your blinds fit correctly first time.
