The maximum size of an email, including attachments, that can be sent or received through Gmail is 25 megabytes (MB). This limitation is a key consideration for users when sharing documents, images, or other files via electronic mail.
This size constraint is crucial for maintaining the functionality and speed of email servers and networks. Imposing a limit helps prevent overloading systems with exceptionally large files, ensuring consistent and reliable delivery for all users. Historically, email systems have had size limitations to accommodate varying internet speeds and storage capacities.
