Concise answer
There is no reliable graft number without measuring the planned area and examining donor density, hair calibre, curl, colour contrast and existing hair. A lower hairline usually requires more donor supply.
Graft planning begins with long-term design and coverage priorities rather than a package size advertised online.
Two people with a similar-looking recession may need different plans because their hair characteristics and future loss risk differ.
When evaluation may help
An in-person donor and recipient assessment is needed before a surgeon can discuss a responsible range and whether surgery is suitable.
