# Item size > [!warning] Watch Out! > The maximum item size in DynamoDB is **400 KB**, which includes _both_ the length of [[Attributes|attribute]] names and their values. ## Example For example, consider an item with two attributes: one attribute named "`shirt-color`" with value "`R`" and another attribute named "`shirt-size`" with value "`M`". The total size of that item is **`23` bytes**. | Name | Value | Space Used | | --------------- | ----- | ---------- | | "`shirt-size`" | "`M`" | 11 bytes | | "`shirt-color`" | "`R`" | 12 bytes | | | | **23 bytes total** | ## Item size for tables with [[Indexes|Local Secondary Indexes]] For each local secondary index on a table, there is a 400 KB limit on the total of the following: - The size of an item's data in the table. - The size of corresponding entries (including key values and projected attributes) in all local secondary indexes.
