This mesh bag measures 19" x 23". Media performs best as a filter when it is not in a bag, but unless you have a filter specifically made for loose lava rock or other media (like the Helix Bio Mechanical Waterfall Filter or Bio Mechancial Reactor), many people will prefer keeping their media in a bag for easy removal and rinsing.
