White Cordless 1 in. Vinyl Mini Blind - 23 in. W x 64 in. L

You can cut off slats if you want to make them shorter. Use the process in the YouTube video by Miche Hacks. You don't need to cut the two raising and lowering strings (two strings in my 29" and 35" versions), which probably does it also but is more risky. You just end up having to cut and tie the middle ladder rung to get it around the bottom bar (as opposed to sliding the bar out of the rungs, then sliding it back in). Way less risky to cut a rung and tie it around the bottom bar. Watch her video.

The 39 inch blind is actually 38.5 inch wide.

No cord. Just lift or pull down from the bottom.

Not all of them do.The only thing you could do is purchase what you like and compare before removing your brackets. You could always return them.

The 35 inch blind is actually 34.5 inches wide.

Yes. Easy to raise. Lift from the bottom. Pull down to close.

This is the low cost model and cannot be made narrower but Home Depot does have blinds that can be custom cut to width. The actual size is 1/2 inch narrower than the stock size. When you see the premium price to allow you to cut to width you may consider the standard size will work. I have used them about 2 inches narrower than I like but the blind covered the glass and looks pretty good for the cost.

yes

depends on whether you want them to sit inside the window (is there room?) or above the window and overlap the widow for more privacy?? If you are not sure take a pic with your cell phone and good measurements. Go to Home Depot and associate will assist you
