How to tell if hermit crab is a male or female

Is there a way to tell if your hermit crab is a female by seeing how big it is? If it's big does it mean it's a female? I have 5 hermit crabs and still can't figure out the gender of them without the hard thing trying to find their gonopores. Is there any other ways to tell of the gender of my hermit crabs? Thankyou!(:(:(:

Females also have hair like appendages on their abdomen which can only be seen when they changing shells. They called pleopods.

Edit. Otherwise no, size, colour, hairyness or other physical features besides gonopores are not reliable.

Females have 2 dots at the base of their rear legs. These are genopores which is where they place the sperm sacks the males pass to them during mating. Males don't have any dots.

I've been able to see the undersides of 2 of my babies and am pretty sure those 2 are females. 3 others yet to be checked.
