What size hooded towel should I buy for a newborn?

A repeatedly upvoted r/BabyBumps comment warns that true 'baby' sized towels (around 30x30 inches) are outgrown within months, and recommends buying toddler or kid-sized hooded towels (closer to 35x35 or larger) for longevity. If you specifically want something for the first few months of swaddle-style wrapping, 29–32 inch towels work; otherwise size up.
