Character Limits for Data Types

Hi all,

I had just been researching on the different character limits for data types. So from my understanding of text data type, these are the following limits.

Text - 255 characters

Long Text - 4000 characters

Extra Long Text - 64000 characters 

To my knowledge these are the 3 available options for any VARCHAR in record types, I was just wondering if this information is correct, wanting clarification please. 

Couldn't really find a clear answer on the limits.

Note: I believe that for record types, there's a limitation for Extra Long Text, limited to only 3 fields within a record type that's allowed to have the Extra Long Text data type.

These limits apply to synced records and any text exceeding these limits will be truncated.

You can find this limitation when you configure fields in a record (see below).

And, keep in mind, that these "characters" are actually bytes. So, if you want to store emojis only, you have to divide the number by 4 as each emoji takes 4 bytes to store.

You will also notice that in the data preview of the Record type, there are no missing characters, persisting bytes beyond the record field limit is also no problem as long as the database field can cater to it.Only when the data is queried that it gets truncated.
