Is English mastiff bigger than saint bernard?

Everything I've read tells me that the English Mastiff is the largest dog breed in the world. The ones I've seen are bigger than the one or two St Bernards I've seen. We're talking a 300 pound dog here!

Autchully the English mastiff weighs about 290 for males they can but the minimum is about 267 pounds The st.benard wouldn't fight the English mastiff because the St.benard has to be in a cold cliement but if they didnt the mastiff would win because it outweighs it and it is the biggest house-outside dog in the world other than the codiac or bear or black bear or anything else the English mastiff and stbenard are biger than even the Hyeana.
