When we called Magneshade (spoke to Ashley, the office manager and very nice), we asked specifically about the shade for the smaller windshield. She checked with the fabricator and explained how the shade was sized to allow appropriate placement of the magnets--meaning the larger windshields do have lack of coverage at the very top where the darker tint is.
I recommend giving them a call -- they really know their stuff and are great to work with. As previously mentioned, they made templates for our side windows when we were there to ensure they had correct measurements should anyone want to order those. We're contemplating interior shades as "one of us" doesn't want exterior magnets, which they use for the side shades.
