The Size of Column of int(11) in MySQL in Bytes

📊💾

Have you ever wondered about the size of a column of int(11) in MySQL? Do you want to know what's the maximum value that can be stored in this column? If you've been struggling with these questions, you're in the right place! In this blog post, we will explore the answers to both of these questions and provide you with easy-to-understand solutions.

Understanding the int(11) Data Type

In MySQL, int(11) denotes a column that can store signed integers, which are whole numbers that can be positive, negative, or zero. The number in parentheses, in this case, 11, indicates the display width of the column when it is retrieved. However, it does not affect the storage requirements.

😮💡

The Storage Size of int(11)

Contrary to what the number 11 might suggest, the storage size of int(11) is 4 bytes. This means that each value stored in this column will take up 4 bytes of memory. Regardless of whether a value inserted into this column is 1 or 11 digits long, it will still occupy the same amount of space.

😲💪

The Maximum Value

The int(11) data type in MySQL can store a maximum value of 2,147,483,647. This maximum value corresponds to the signed 32-bit integer range. Any value larger than this maximum will result in an overflow.

🛠🔐

Solutions and Recommendations

Here are a couple of solutions and recommendations to help you work with columns of int(11) more effectively:

1. Choose the Data Type Wisely: Always consider the range of values you need to store when selecting a data type. If your values can exceed the maximum value of int(11), consider using a larger data type such as bigint instead.

2. Optimize Storage: If you have a large table with millions of rows and memory optimization is crucial, consider using smaller integer data types like tinyint, smallint, or even mediumint if they meet your requirements. These data types occupy less space compared to int(11).
