What is the max length of VARCHAR in MySQL?
0 to 65,535
Values in VARCHAR columns are variable-length strings. The length can be specified as a value from 0 to 65,535. The effective maximum length of a VARCHAR is subject to the maximum row size (65,535 bytes, which is shared among all columns) and the character set used. See Section 8.4.

Should I always use VARCHAR 255?
In short there isn’t much difference unless you go over the size of 255 in your VARCHAR which will require another byte for the length prefix. The length indicates more of a constraint on the data stored in the column than anything else. This inherently constrains the MAXIMUM storage size for the column as well.

Is VARCHAR max 255?
Is VARCHAR 8000 the same as VARCHAR Max?
About varchar(MAX) If your data is longer than 8000 characters varchar(MAX) is what you need. You can store up to 2GB size of data this way. In varchar(MAX) fields if your data size is shorter than 8000 characters your data is stored in row automatically (therefore the data execution is faster).
Why is VARCHAR 255 so common?
0-255 is a single octet or 8 bits or 1 byte. Computers work in binary. Binary being hard to convert to base 10 (decimal) we use binary to hexidecimal conversion which is more easily converted to the easily read and well loved base 10 we all read. So 255 is really FF which is actually 8 “on” bits or 11111111 in binary.

This orders the results in ascending order, which lists the minimum value first. – Find the Maximum Character Length.
