I have 2 of these giant versions and they are definitely larger than the regular ones you find on the market, I struggled with cloth masks in the past, due to the small size they only just fit over my mouth and nose and were uncomfortable to wear for long periods, which isn't the case here.

The Venum Giant mask covers a large part of my face (and I have a fat face), with nose and mouth well covered, it also sits nicely under the chin due to the design, and covers the nose well. The nose section also has an integrated clip that you can squeeze to hold in place.

I find the masks to be comfortable when worn for long periods, although due to their nature and design air flow is reduced when compared to the medical masks.

No official measurements, even on the Venum website, but measuring mine it is 24cm wide (not including the ear hooks) x 30cm tall

Highly recommended.

I hope that this helps.
