# Maximum allowed attachment size

Configure the **com.glide.attachment.max\_size** property to control the maximum size \(in megabytes\) permitted for an uploaded attachment.

The **com.glide.attachment.max\_size** system property controls the maximum size of uploaded attachment in megabytes. If the value of property **com.glide.attachment.max\_size** is 1024 then the max allowed attachment size is 1Gb.

**Note:** A real attachment size is calculated through multiplication 1024 \* value of the **com.glide.attachment.max\_size** property.

Ensure that the property **com.glide.attachment.max\_size** is set to `1024` or less.
