The opening measures 36 inches wide by 72 inches tall, and the shop quotes 10 mm tempered — the standard shower make-up. In the main panel you pick the rectangular shape, enter the two dimensions, and tap the 10 mm preset. The engine computes 18 square feet of face area and, through the tempered density of 2.52 g/cm³, a net weight of roughly 92 pounds — about 42 kilograms. The whole first layer of the tool took four inputs and about ten seconds.
The second layer is already done: the glass type selector applied tempered density automatically, and had the panel been part of a double-glazed screen, the glazing multiplier would have doubled the pane count in the same keystroke. The third layer is where the number becomes a plan. Toggle the 10% safety margin and the planning figure rises to about 102 pounds — the number to size suction cups and storage against, not the bare 92. The handling block reads the result and delivers its verdict honestly: a 42 kilogram panel is a two-person lift with suction cups, full stop.
Notice what the outputs also handed you: a surface weight just over 25 kg/m², which is the figure the hinge manufacturer schedules against, and a per-piece weight that sizes the delivery. One panel, four inputs, and every downstream decision — hardware, crew, transport, storage — has a defensible number behind it. That is the entire product philosophy of the site in one walkthrough: the math is yours to check, the margins are yours to set, and the handling advice refuses to flatter you.
