Question: What The Maximum Size I Can Attact In Gmail.com?

Answer:

You can attach maximum 20 megabytes sized files. And it’s not accurate 20 MB. This maybe 17 to 20 MB files can send to any gmail user. If you want to send any other user such as yahoo mail, hotmail, aol it’s not possible to send the mail.

If you exceed the 20 MB size, automatically gmail displays a warnings that you exceed 20MB. So, you can split the file and send with two mails.

Or you can invite your friends to signup gmail and then 20 MB mail to your friends. It’s simple for both side.
