Guide to Outside Mount vs. Inside Mount: What to Know Before You Choose
The choice between inside mount and outside mount blinds depends on the window recess, desired appearance, light gaps, hardware clearance and installation surface. Neither method is automatically better for every window.
What Is an Inside Mount?
An inside mount places the blind within the window recess. It can create a clean, integrated appearance and works well when the recess is deep enough and free from obstructions.
What Is an Outside Mount?
An outside mount places the blind on the wall or surface outside the recess. It is useful when the recess is shallow, uneven or unsuitable for mounting a blind inside.
| Consideration | Inside mount | Outside mount |
|---|---|---|
| Appearance | Clean and built-in | Can make the window treatment more prominent |
| Light gaps | Usually more side gaps | Can cover more of the opening |
| Recess requirement | Needs suitable depth | Less dependent on recess depth |
| Obstructions | Handles and frames may interfere | Often easier to clear obstructions |
| Privacy | Good when correctly fitted | Can provide broader coverage |
When Inside Mount Makes Sense
- The recess has sufficient depth.
- The window frame is suitable for fixing.
- Handles do not obstruct the blind.
- A built-in visual effect is preferred.
- Small light gaps are acceptable.
When Outside Mount Is Better
- The recess is too shallow.
- The frame has handles or other obstructions.
- More window coverage is required.
- You want to reduce visible side light gaps.
- The wall above the opening provides a better fixing surface.
Measure Before Choosing
Do not decide the mounting method from a photo alone. Check recess depth, frame width, handle projection, wall condition, ceiling or pelmet position and the available space around the opening.
Light Control and Privacy
Outside mounting can help increase coverage around the window, which may reduce side light gaps. However, the final result also depends on blind design, fabric opacity and how closely the system fits the surrounding opening.
Bali Villa Considerations
Large glass doors and windows are common in Bali villas. When blinds are combined with curtains, the mounting method should also be considered together with the curtain stack, handles, sliding panels and furniture clearance.
Common Mistakes
- Choosing the mount before checking the recess.
- Ignoring window handles.
- Measuring only the glass instead of the full installation condition.
- Forgetting how the blind will stack or roll.
- Assuming outside mount always eliminates all light gaps.
Simple Decision Rule
Choose inside mount when the recess is suitable and you want an integrated look. Choose outside mount when coverage, clearance or installation conditions make an internal fit impractical.
For custom projects, a professional measurement can confirm the safest mounting method before fabrication. Almeers Living can assess the window condition and recommend the appropriate blind installation approach.
