What is lattice?

A lattice is simply a grid made by crossing sticks or bars over each other to create a sturdy, open structure.

Think about the wooden fence at your grandmother’s house. The vertical slats hold up the top rail, but if you look closely, there are thin pieces of wood diagonal across them in an "X" shape. Those diagonals are part of the lattice. They don't block the wind or rain like a solid wall does; they let air and light pass through while still keeping things contained.

You might wonder why we use crossed lines instead of just straight ones. Imagine trying to push down on a single stick versus pushing down on two sticks that cross each other. When pressure hits one, the other helps share the load. This is what makes a lattice so strong for its weight. It uses less material than a solid block but stays very tough.

You see lattices everywhere without noticing them:

• The crust on a fruit pie keeps the juice inside while letting steam escape.
• A basket weaves sticks together to hold your apples without crushing them.
• Even the metal mesh in a colander is a type of lattice that lets water drain but holds the pasta.

So, when you hear the word lattice, just picture a net or a grid. It is nature and builders using simple crossings to make something strong yet light, open yet protective.
