Your blinds can be fitted inside the window frame ("inside fit") or outside of the window on the wall or architrave ("outside fit").
You'll need to decide which option you wish to go with before you measure.
Inside fit is typically the preferred choice, as it delivers a sleek appearance that's more visually pleasing than an outside fit. It's worth noting that some light will filter through the edges though. This can be reduced to some degree by adjusting the blind's position within the frame.
If you are considering Inside Fit, check for any obstacles such as fixed mullions or sliding door mullions that might hinder installation on the inside of the window frame.
Outside fit, while less common, has its advantages. It may be the preferred option in these situations:
- its different distinct aesthetic appeal
- its ability to provide better light blockage when combined with a blind that is back rolled - This can be particularly beneficial in bedrooms.
- it is also a good option for irregularly shaped windows or windows with shallow frames.
