Measurement chart?

Hi. I am looking for a chart that has children’s sweater measurements in inches for different ages. A pattern I have lists only finished chest measurements, not ages. Is there a chart that gives basic lengths of garment, shoulder seams, sleeve lengths, sleeve starts and ends, neck scoops, etc.? I would like to make a sweater for my niece who is 2 now but I want it for her for next year… so I can’t actually measure her for it and I don’t have any clothes for a 3 yr old to measure. If I have the general measurements then I can figure out how many stitches based on my yarn and gauge. Thanks for any help.

I found this

Measurements for Standard Clothing Sizes

Thank you so much!!! That is EXACTLY what I was looking for. That helps so much.
Thank you!

Here is another good reference website:
There is a PDF on the site that you can print out. Hope that helps!
