How to force installation of standard-width blinds for window with nonstandard dimensions

windows

I want to install blinds on a window that has a 27.5-inch width. But it looks as though 27.5inches is not a standard width; it's easy to find widths of 23, 27, 29, 30, I don't see 27.5 inch blinds anywhere. I did just find these 27 inch blinds, however. Is there a DIY way to customize 27 inch blinds so that they can be installed on a 27.5-inch wide window?
Alternatively, would buying 28-29 inch blinds, and sawing them down to 27.5 inches work?

Please remember to keep answers specific to the problem at hand. Thanks.

Those 27 inch blinds you link to are top mount and will fit in a 27.5 inch opening without modification. But there are also side mount ones that would also work but you would need to add a 1/4 inch shim to both sides or a 1/2 inch shim to one side.

Most blinds can't be simply cut down in width except those that are designed to be cut to length.
