There's no easy way to tell. If you don't know the hatch date yourself and the person who sold it to you is unsure as well, there are only rough guidelines to use.
Note: Counting spots doesn't work.
It's nearly impossible to tell the exact age of any reptile by looking at it, since many factors will effect how fast it grows: If it's fed to much, it could grow faster then normal. If its neglected and not fed enough its growth can easily be stunted. If its in a cage too small, it's growth could be stunted as well.
Telling the age of any reptile is often hard because the way it grows is directly proportionate to how it is fed, what their environment is like, and it's overall care. However, I have owned Eyelash Crested Geckos and I have found this method of keeping track of them to be helpful...and pretty easy...There are also ways of measuring their weight as well. Remember, this is only an estimate, most healthy Geckos should be in this general range.

Baby geckos are about 1-1.5 inches. Adolescents are about 2-3 inches. Adults are about 4 inches plus.
my leopard gecko has also stopped eating and she is pretty old too so I think this might be the case. 19 is fairly old for a leopard gecko to live.
26
I would say somewhere by 8/12 month's possibly more depending on the leopard gecko.
When a leopard gecko feels threatened it loses its tail. The tail still moves because it has nerve endings in it, and will distract the enemy while the leopard gecko gets away. Eventually the leopard gecko will grow a new tail but it will not be as pretty as its old tail. It will grow back in a "light bulb" shape instead of sleek and straight.
Leopard geckos are nearly impossible to sex when they are young. When they are about a year old, you can tell by looking at two things. Their head: males have a broad head, and females have narrow heads Their private area: males have visible pores
If properly cared for, any Leopard Gecko can live up to 20 years.
Pinky mice and day old chicks.
about 4 or 6 inches
go to the vet
Can start feeding them mealworms immediately. Leopard gecko really like crickets, so if crickets are always available do not expect them to eat many mealworms.
On average, the leopard gecko will live 5-10 years in the wild due to predators but in captivity, the oldest recorded leopard gecko lived to be 27 years old. Youtube "dink the leopard gecko"
no they are not poisonous and are docile but just make sure the gecko inst sick leopard geckos can carry salmonella and other diseases.
