1 byte for the length, and the actual storage for the rest. 255 is the max limit, not an allocation. 255 is not the max limit. There is a variable MAX you can use which Varchar(max) stores a maximum of 2 147 483 647 characters.
Is VARCHAR max 255?
Storage Information : 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. Make sure you are aware of the effects of a multi-byte character set. VARCHAR(255) stores 255 characters, which may be more than 255 bytes.

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 255 the max?
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.
How many texts is 255?
Answer: 250 characters is between 40 words and 60 words with spaces included in the character count. If spaces are not included in the character count, then 250 characters is between 40 words and 80 words.
