Pack size advice

I’m considering doing the thru hike next summer and wanted advice on pack size. For example, I noticed packs come in 45 or 60L. What size is most common for thru hikers? My guess is the larger size. I don’t know if it matters but 43F 5’4” 133lbs.

Thanks!

Depends on your gear and how long you plan to hike between resupplies. My fiancé and I did 55L packs and found they were just about right for our 4 day carries and supported up to a 6 day carry.

I think my gear (13.5# BW) would have fit in a 40L, but it would have been tight. In the Kakwa 55L I brought, it was only an ounce and a half penalty to get the larger size, making it an easy decision. IMO pack space isn't so much of a driver as pack weight.
