Actual size of the hinged glass piece is 15.5x6 inches. It would be nice if this was listed on the box or in the description. It comes with a back piece you can cut to fit the width, cut out space for your accessories, etc. If you have a 16" aquarium obviously the top has to be a little smaller to fit inside and sit on the rim edges, but 15.5 was too wide for my aquarium, by a quarter inch or so, I am seeing this same thing in a couple other reviews. I don't know what brand this aquarium is, was given to me by a friend who upgraded their aquarium. I was disappointed because I had previously got the 10 gallon aqueon hinged lid and it fit my Marina 10 gallon aquarium and I love it. I don't like the black plastic lids with the built in lights that come with most kits. That setup means when you open the lid to do something in the tank you are losing your light. The hinged glass lid fixes this, unfortunately this one was just too wide for my tank. Post the actual size of your product, not the size of the aquarium.

Bought today, drove home and was 1/4 inch to big length wise for my aquarium. Ended up having to use a glass cutter to make glass panes right size to fit. Better than being to short but more of a project than expected

This top is very nice quality and fits perfectly on my aqueon 5.5 gallon tank. The only problem is that it does make it hard to have a filter or other accessory that hangs on the rim of my tank.

The glass fits perfectly on all sides, however, the vynl strip is about a centimeter top wide and doesn't sit flat on the lip of my aquarium. Also the vynl is INCREDIBLY hard to cut. I just took it off because it was in the way of my internal filter, which will lead to evaporation unfortunately. But at least the majority of the water is covered now 🤷‍♀️ ugh

these lids are advertized as 16 inches and designed to fit the 5.5 gallon aquarium, but they actually measure 19 inches and don’t at all fit the aquarium. really frustrating because this was the only glass lid i could find that was supposed to fit my aquarium

I'm really disappointed because I am either going to have to buy a different lid or try to cut the glass to size myself. The glass doesn't seem to be cut square and it's about 1/8-1/4" too long on one side, so it doesn't seat properly on the rim. I would actually really like the lid if it fit properly.

Mine came with a missing back Velcro strip by we still makes it work pretty good product and pretty good price

I just purchased this item today from Petco in Branson, MO., for a 10gal medic tank that I'm setting up. Part of this aquarium lid comes already together, you have to "Safely Connect" the clear plastic canopy strip to either glass panel that you want to face the rear of your tank. I got the plastic canopy back strip attached safely and with no issues, but the glass is a bit sharp in certain areas - use caution. When I finished, I placed the lid onto the inner rim of the tank - only to find out this lid it's about a 1/4" to short(front to back) - side to side it fits great. Would be nice to see this Aqueon Versa Top, fit an Aqueon Standard 10gal tank. Date on bottom of box has "Jun2017", tank size hasn't changed in almost 6 years has it?
