Size of Baby Hats

Is there any accepted length of hat for newborns for distance from brim to top of hat? TIA

Hat Sizes

Is this the sort of thing you mean? Of course, it can vary, but I take it as a starting point.

Bev’s Country Cottage offers size charts, including size charts for hats, including circumference and hat height for preemies and babies of various sizes (weeks of gestation).

Happy knitting!

Looks like 5.5" to 6" might be a length to go for. Thanks for the input!

You’re welcome, @annekepoot .
Did you notice, @WeeBizzom and I both posted in the same minute!
