change the length of field in the registration for

Hello,
All the fields in the Hikashop Registrationform have from scratch the same length.
I know how to change the length of the field from the adressdata, but where/how can i change the lengt of i.e. User (Naam), username (Gebruikersnaam), emailadress, password, etc.
See attachement and you see what i mean.

So sorry i don't understand the question 100% but I'm gonna give it a chance and guess the answer.
Go to Components>Hikashop>Display>Costume Fields>(pick a field you like) and change the "Size" to 50 (just for start).
Hope this helps.

Thank you for your reaction.
Yes i know how to change the field in the Custom Fields. But the fields i mean (username, emailadres, password etc) are not mentioned here. That is my problem.
Thanx anyway.
