What's the difference between VarChar, Text and Memo in Microsoft Access?

TEXT: The Short Answer. If you're looking for a TL;DR, it's this: use VARCHAR if your data is of variable length and you know it fits into VARCHAR's 65,535 character limit. In most circumstances, VARCHAR provides better performance, it's more flexible, and can be fully indexed.
Some Differences Between VARCHAR and TEXT A VARCHAR can be part of an index whereas a TEXT field requires you to specify a prefix length, which can be part of an index. VARCHAR is stored inline with the table (at least for the MyISAM storage engine), making it potentially faster when the size is reasonable.
CHAR columns should be used for columns that vary little in length. String values that vary significantly in length and are no longer than 8,000 bytes should be stored in a VARCHAR column. If you have huge strings (over 8,000 bytes), then VARCHAR(MAX) should be used.
CHAR items, which are fixed length, are the fastest to store and retrieve but can waste storage space. VARCHAR, a variable-length string, can be slower to store and retrieve but does not waste storage space. TEXT is a character BLOB that requires more storage space and I/O than the other two.
It is a data field that contains a variable amount of text. These texts are kept stored in a companion file but considered as a portion of data records. Access memo data type holds up to 65000 characters if it is entered through the Access interface. And if the text is entered programmatically then it can hold up to 1 Gigabyte.
Within Access Table, text fields are bounded to only 255 characters. Whereas, the Memo fields can handle up to 64,000 characters which are about 8 pages of single-spaced text. Instead of that, sometimes MS Access Memo Field Truncated or get cut off.

This type of data type has the capacity to store 255 characters, but by default, the field size is about 50 characters. For entering a large number of characters in a Text field FieldSize property controls is been used. If you required to keep more than 255 characters then make use of the Memo data type. As it can store up to 65,536
