Rimmed Aquarium Measurements

Rimmed Aquariums will require at the minimum a width and depth measurement. If cord slots and/or cutouts are selected, they will need the lip and outer frame measurement as well. For a precision fit, measurements must be provided to the nearest 1/16". We will offset your measurement to ensure the lid fits the specified opening. Accuracy of these measurements will be a direct reflection to the fitment of your lid and is the customer's responsibility to provide. If using a tape measure with a metal clip at the end, please ensure it is fully extended when using to take measurements.

The width measurement is a left to right measurement of where the lid will physically sit. This measurement also includes the rimmed aquarium lip which the lid will rest on. The lid must be supported on ALL sides by the rimmed aquairum lip.

The depth measurement is a front to back measurement of where the lid will physically sit. Like the width measurement, this measurement also includes the rimmed aquarium lip which the lid will rest on. The lid must be supported on ALL sides by the rimmed aquairum lip. Note: Take multiple measurements from different parts of the aquarium. If there's a difference of more than 1/8" between measurements, it indicates bowing in the tank. In such instances, we advise replacing the aquarium, as our lid may not fit correctly in this scenario.

The lip measurement is from the middle of the rimmed aquaiurm frame where the lid extends to measured inward to the most innermost part of the rimmed aquarium. This measurement is only necessary if cord slots and/or cutouts are needed.

The outer frame measurement is from the middle of the rimmed aquaiurm frame where the lid extends to measured outwards to the most outermost part of the rimmed aquarium. This measurement is only necessary if cutouts are needed.
