# Size Property (ADO Stream)
Indicates the size of the stream in number of bytes.  
  
## Return Values  
 Returns a **Long** value that specifies the size of the stream in number of bytes. The default value is the size of the stream, or -1 if the size of the stream is not known.  
  
## Remarks  
 **Size** can be used only with open [Stream](../../../ado/reference/ado-api/stream-object-ado.md) objects.  
  
> [!NOTE]
>  Any number of bits can be stored in a **Stream** object, limited only by system resources. If the **Stream** contains more bits than can be represented by a **Long** value, **Size** is truncated and therefore does not accurately represent the length of the **Stream**.  
  
## Applies To  
 [Stream Object (ADO)](../../../ado/reference/ado-api/stream-object-ado.md)
