Maximum Attachment Size to Gmail is now 25 MB
Google has increased the maximum size supported for Gmail attachment from 20 MB to 25 MB. It is a very good news for Gmail users and it is useful if you often transfer large files between your family and friends.
Google blog reported that Gmail users can send and receive messages up to 25 megabytes (MB) in size. Note that you may not be able to send larger attachments to contacts who use other email services with smaller attachment limits. If your attachment bounces, you should invite them for Gmail account.
