Welcome to another Helpdesk article where we answer common questions which are asked by our users. One of users recently emailed us to ask us a simple question. "What is the attachment size in Gmail?"
Well, the simple answer to this question is that Gmail supports attachments whose size are 25MB in size. This means that you can send and receive attachments up-to 25MB in size. However, when you send other email services might not accept attachments that large and might reject the email.
However, there are several other ways in which you can send emails larger than 25 MB as well. For example, you can send 100MB attachments with Yahoo Mail or even send large attachments up-to 5GB in Outlook.
Additionally, you can also use services like WeTransfer to send attachments up-to 2GB through email. The key with this is that, you don’t attach the actual files to the email itself, but instead make use of an external online file storage service which allows you to upload large files and then add the link provided by them to the email.
Hope this answers your question. You might also want to read several of our Gmail Tips to find information on how you can work better with the email service.
