Predicting adult ear length on an English Lop is not an exact science. From the age of six weeks on until the age of 16 weeks (approximate age of ear growth completion), on average, one can expect a total of 6" growth in addition to the measurement taken at the age of 6 weeks. Between 6 and 8 weeks of age, one can expect on average 2 1/2" of growth; 8 to 10 weeks another 1 1/2"; 10 to 12 weeks - 1"; 12 to 14 weeks - 1/2".
The following guideline may help in determining final ear length in an adult based on junior length:
Length at Six weeks: Expected Senior length:
15" 21"
16" 22"
17" 23"
18" 24"
19" 25"
Further growth of approximately 1/2" may be obtained through skull development.
THATS THE EAR CHART I WAS LOOKING FOR.
