Answer 1

Worked perfectly for me to calculate SQL database size in SQL Server 2012

exec sp_spaceused

Answer 2

If you want to simply check single database size, you can do it using SSMS Gui

Go to Server Explorer -> Expand it -> Right click on Database -> Choose Properties -> In popup window choose General tab ->See Size

Answer 3

EXEC sp_spaceused @oneresultset = 1 show in 1 row all of the result

if you execute just 'EXEC sp_spaceused' you will see two rows Work in SQL Server Management Studio v17.9

Answer 4

Check Database Size in SQL Server for both Azure and On-Premises-

Method 1 – Using ‘sys.database_files’ System View

SELECT
    DB_NAME() AS [database_name],
    CONCAT(CAST(SUM(
        CAST( (size * 8.0/1024) AS DECIMAL(15,2) )
    ) AS VARCHAR(20)),' MB') AS [database_size]
FROM sys.database_files;

Method 2 – Using ‘sp_spaceused’ System Stored Procedure

EXEC sp_spaceused ;

You can check how this query works following this link.

    IF OBJECT_ID('tempdb..#spacetable') IS NOT NULL 
    DROP TABLE tempdb..#spacetable 
    create table #spacetable
    (
    database_name varchar(50) ,
    total_size_data int,
    space_util_data int,
    space_data_left int,
    percent_fill_data float,
    total_size_data_log int,
    space_util_log int,
    space_log_left int,
    percent_fill_log char(50),
    [total db size] int,
    [total size used] int,
    [total size left] int
    )
    insert into  #spacetable
    EXECUTE master.sys.sp_MSforeachdb 'USE [?];
    select x.[DATABASE NAME],x.[total size data],x.[space util],x.[total size data]-x.[space util] [space left data],
    x.[percent fill],y.[total size log],y.[space util],
    y.[total size log]-y.[space util] [space left log],y.[percent fill],
    y.[total size log]+x.[total size data] ''total db size''
    ,x.[space util]+y.[space util] ''total size used'',
    (y.[total size log]+x.[total size data])-(y.[space util]+x.[space util]) ''total size left''
     from (select DB_NAME() ''DATABASE NAME'',
    sum(size*8/1024) ''total size data'',sum(FILEPROPERTY(name,''SpaceUsed'')*8/1024) ''space util''
    ,case when sum(size*8/1024)=0 then ''divide by zero'' else
    substring(cast((sum(FILEPROPERTY(name,''SpaceUsed''))*1.0*100/sum(size)) as CHAR(50)),1,6) end ''percent fill''
    from sys.master_files where database_id=DB_ID(DB_NAME())  and  type=0
    group by type_desc  ) as x ,
    (select 
    sum(size*8/1024) ''total size log'',sum(FILEPROPERTY(name,''SpaceUsed'')*8/1024) ''space util''
    ,case when sum(size*8/1024)=0 then ''divide by zero'' else
    substring(cast((sum(FILEPROPERTY(name,''SpaceUsed''))*1.0*100/sum(size)) as CHAR(50)),1,6) end ''percent fill''
    from sys.master_files where database_id=DB_ID(DB_NAME())  and  type=1
    group by type_desc  )y'
    select * from #spacetable 
    order by database_name
    drop table #spacetable

Also compare the results with the following query's result

EXEC sp_helpdb @dbname= 'MSDB'

It produces result similar to the following
