Size (external kerb)
Standard lanterns run from 1000mm to 4000mm on each side.
Measure the outside of your kerb, not the hole
Every lantern is made to the external kerb size: the outside face of the finished upstand, over the waterproof membrane. Measuring the internal opening is the single most common ordering mistake, and it produces a unit that will not fit. If you are unsure, send us a photo and we will check it before we order.
Sizes between our standard sizes are priced at the next size up. We still make the lantern to the exact size you enter here.
