Approx 7 1/2”

I crochet loosely and my stitches tend to be a little tall. Gauge is not crucial in something like this. There are so many options for these squares!

I would do 24 squares, 8x3 to make a rectangle shawl.
12squares / 4x3, could make a nice baby blanket.
Just measure your square once finished, put as many together to get the width that you want and the length that you want.
Make a front and back for a sweater, connect at shoulder, connect at side leaving armholes, crochet sleeves if you want.
Make a lap / wheelchair throw or a couch throw/afghan.
Use the pattern to make washcloths, pillow covers. There are so many options
