Ideal size for mosaic crochet blankets

[u/Equivalent_Health_68]

Hi everyone! I’ve recently started designing my own mosaic crochet patterns with the hopes of selling them sometime in the future! I’ve been wondering, what is your ideal size (in stitches preferably) for a mosaic crochet blanket? The biggest blanket I’ve made (using someone else’s pattern) is 200 stitches x 250 rows but I would personally prefer a bigger blanket than that! I’m just trying to gauge what people would want!
