Listing Sizes of Tables in Database in SQL Server

Hello to everyone,

In this article, I will try to give information about listing the dimensions of the tables in the database in SQL Server.

In SQL Server, in some cases you may want to list the sizes of the tables in the database.

You can easily do this using the code below.

SELECT t.name AS TableName,
       s.name AS SchemaName,
       p.rows AS RowCounts,
       SUM(a.total_pages) * 8 AS TotalSpaceKB,
       SUM(a.used_pages) * 8 AS UsedSpaceKB,
       (SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB
FROM sys.tables t
    INNER JOIN sys.indexes i
        ON t.object_id = i.object_id
    INNER JOIN sys.partitions p
        ON i.object_id = p.object_id
           AND i.index_id = p.index_id
    INNER JOIN sys.allocation_units a
        ON p.partition_id = a.container_id
    LEFT OUTER JOIN sys.schemas s
        ON t.schema_id = s.schema_id
WHERE t.name NOT LIKE 'dt%'
      AND t.is_ms_shipped = 0
      AND i.object_id > 255
GROUP BY t.name,
         s.name,
         p.rows
ORDER BY UsedSpaceKB DESC;

When you run the above code, you will see a result similar to the one below.

As you can see, the sizes of the tables in the database are listed.

Good luck to everyone in business and life.
