Choice of canvas options has proven to be worth a little bit of explanation, as the variables can affect where you display the picture, how it lasts, and whether you need to frame it.
"Standard" depth for a canvas is .75", designed to be displayed in a frame nearly 100% of the time, although there are exceptions.
"Gallery Wrap" can imply a number of different profile depths, usually from 1 3/8" to about 2.5". These can be displayed framed or unframed, and can stand on shelves or countertops. If my commission indicates they intend to leave the picture unframed, or is unsure if they will frame it, my preference is to paint pet portraits larger than 5x7 on a 1.5" canvas depth to give them options.
This 1.5" canvas depth works well in a frame with a float edge, or without a frame at all.
