Glass tabletops are transparent so they don't mask the table legs or base. End tables, coffee tables, dining room tables and outdoor patio tables use glass as tops. Glass has easy upkeep and doesn't need polishing as wood does to maintain its clarity, although glass does chip if a heavy item hits it. Ordering a new glass tabletop enables the replacement of a chipped top or a new style of edging in a different color to match your décor.
Place the tip of a measuring tape on the center of the table vertically. Stretch the measuring tape straight across to the opposite side. Use this measurement as the diameter and size for a round table top. Use this measurement as the size of a square tabletop or the width of a rectangular tabletop. Write down the measurement on a single piece of paper.
Measure the length of a rectangular tabletop from edge to edge. Write down the length.
Place the tip of a measuring tape underneath the edge of the tabletop. Stretch the measuring tape up and read the number on the tape where the tabletop upper surface meets the measuring tape. This is the thickness of the tabletop. Write down the thickness.
Measure the size of all cutouts and notches in the glass tabletop, so they can be precut for you. Measure the diameter of a hole in the center for a patio table to accept an umbrella. Measure any notches on the perimeter of the tabletop that are used for mounting purposes. Write down these measurements and draw a diagram of all cutouts, notches and holes.
Look at the edge of the glass to determine the type of edge fits the table. A pencil edge is a flat, thin edge. A beveled edge drops off from the top portion to the bottom portion of the glass. A polished edge is thicker than a pencil edge with polished bright glass around the perimeter. A wavy edge has indentations around the perimeter. Write down the type of edge.
Add the shape, type and color, if applicable, of glass to the measurements.
