Buying Guide

Confirm inset diameter

Measure the inner lip of your side table's inset ring so the replacement glass—commonly 18, 20, or 24 inches—seats snugly without gaps

Choose tempered glass

Tempered glass is heat-treated to resist breakage and, when it fails, shatters into small blunt pieces rather than large shards, making it the standard for outdoor tabletops

Check edge finish

Beveled or polished edges improve aesthetics and reduce chip risk on exposed rims; confirm edge style if your table's inset shows the glass edge

Match thickness to support

Select a thickness rated for side-table loads—thicker tempered glass increases stiffness and reduces flex under weight, improving durability

Prioritize fit over extras

A correctly sized, tempered glass top commonly offers better long-term value for an inset side table than features like decorative coatings or unnecessary extras
