Measure both the width of the window and the height of the window. Consider adding an extra 3 inches to the width and height for optimum light control and privacy. Extending the blinds outside the window will also provide the space needed for the mounts and help the window appear larger than it actually is.
Measure the width to the nearest 1/8 of an inch between the outermost points where you'll place the blinds. For optimum light control, the blinds should extend 1-1/2 inches beyond the window opening on each side.
Optimal Distance for Inside-Mounted Blinds
For inside-mounted blinds, positioning them as close to the windowpane as possible enhances insulation and light control. A gap of approximately 25-50mm (1-2 inches) between the blinds and the glass is recommended.
It's really up to you and how you want the window to look. It can be more clean to simply put them at the front of the window frame but depending on the depth you may want the room in front for.
The actual width of the 35" blinds are 34.5" (half inch narrower) to comfortably fit inside a 35" opening. So if your frame is exactly 34.5 inches, I would go with the 35" blinds. But first check that the width is the same through the whole length of the frame.
Yes, it is okay for blinds to be too long, but they mustn't be too long. Vertical blinds should ideally overlap the top of your window recess by at least an inch. And, if you do find your blinds are still too long and overlap at the bottom, you can still make slight changes to them afterward.
Privacy: Blinds that touch the sill can improve privacy, especially in spaces like bathrooms or ground-floor rooms. Day and Night Blinds and Roman Blinds benefit from this setup as they prevent gaps through which people can see. Temperature Control: In colder months, blinds that touch the sill can help retain heat.
Factory Deductions: Inside mounted products have a light gap between 1/8” and 1/4” on either side of the window – this gap is required in order for the product to operate properly.
Do blinds have to fit exactly? Yes, if you want to maximise their efficiency in terms of both blocking the light and insulating your window.
Aid in Better Sleep
This is especially important for light-sensitive sleepers or those living in well-lit areas. Closing your blinds ensures that your bedroom remains a sleep-friendly sanctuary, promoting healthier, more restorative rest.
Inside mounts are the most popular choice. They offer a clean, finished look because the blinds or shades are recessed and contained inside the window casing. Inside-mounted window treatments are NOT the best choice for you if: Your window frame is not deep.
For horizontal blinds, we recommend a minimum of ¾ inch overlap on each side, for a total of 1.5 inches of overlap. For vertical blinds, you will want even more overlap: 1.5 inches on either side, for a total of 3 inches.
The big argument in favour of keeping your blinds open is that it's healthier. According to a report in Science Daily in 2018, letting extra sunlight into a room kills bacteria in the dust. In tests conducted at the University Of Oregon, researchers discovered that bacteria prefer dark rooms.

Example: If the window opening is 36” wide, it might be helpful to order 40” if the space allows. This will provide 2” coverage on each side of the window. No deductions/additions will be made to the width ordered.

Yes, for your blinds to work to greatest effect and to achieve the right visual finish, window blinds should rest on the windowsill. The only exception to this is vertical blinds which require a small amount of clearance to prevent the louvres from dragging on the windowsill when operated.
Exact Fitting
To minimize light leakage we recommend that the blind overlaps the window recess by at least 70mm at the top and 50mm each side. The overlap at the bottom of the blind is a matter of personal choice but please take into account obstacles such as radiators.
When nighttime hits, placing your blind's slats in the down position is best.
