Favorite print aspect ratio?

[CarolineJensen]

I tend to adore squares. I think it stems from my love of shooting square with film, way back when. I may be an odd duck, but what aspect ratio is your favorite for printing? Why? 

Does anyone else panic when you have to make a gallery wall with different aspect ratios?  Any tips? My walls are covered in squares, haha!

4x5 because of Instagram! But I find out that my favorite painting by Rembrandts "The Storm on The Sea of Galilee" was this aspect ratio too!

Oh, that is interesting! You can never go wrong following Rembrandt! Interesting that that painting is 4x5!

I don't have a favorite, it is completely dependent on the image.

That is interesting! Thanks, Tony!
