What is the limit of varchar Max?

2 GB
VARCHAR(MAX) is different from VARCHAR because it supports character strings up to 2 GB (2,147,483,647 bytes) in length. You should consider using VARCHAR(MAX) only when each string stored in this data type varies considerably in length, and a value might exceed 8000 bytes in size.

Is varchar Max same as varchar 8000?

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).

How can I store more than 8000 characters in SQL variable?

Is it OK to use VARCHAR Max?

Varchar(max) should only ever be used if the size of the field is known to be over 8K. In every other instance, the size must be specified. Failure to do so is poor design and will lead to performance issues on any but the most trivial of systems.

What is the difference between varchar Max and NVARCHAR Max?

The key difference between varchar and nvarchar is the way they are stored, varchar is stored as regular 8-bit data(1 byte per character) and nvarchar stores data at 2 bytes per character. Due to this reason, nvarchar can hold upto 4000 characters and it takes double the space as SQL varchar.

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.
