There are several fields that are common sense to use with a given standard. The W3C and some other has its recommendations, but the advice on this site are comprehensive. I have made an easy overview that I have made that suits my purposes.
I just quried my databases with thousands of customers in Norway and checked with checked with other people’s recommendations.
This is what I found:
|Name of field||Min||Max|
|The maximum first name length was 46. I go with 50.||2||50|
|Last name was similar to first name: 50.||2||50|
|Full name is sum of the above||4||100|
|2 x Street address maxes out at 95 characters. The long ones were all valid. I always use to address field.||0||100|
|Postal Code (https://en.wikipedia.org/wiki/List_of_postal_codes. Use max 12 if storing dash or space)||2||11|
