Tempered Glass Table Tops
Custom & Standard Sizes
Shop glass table tops by size and shape — round, rectangle, square, oval, and more. Or order a custom-cut replacement table top for a perfect fit, guaranteed.
Choose Your Glass Table-Top Shape
Every shape is available in standard sizes or cut to your own measurements in millimetres.
Thickness guidance: 6 mm or 8 mm clear toughened glass is the typical recommendation. All table tops are cut in toughened (tempered) safety glass — not laminated — in 6, 8, 10, 12, 15 and 19 mm.
In-Stock or Custom Cut to Size?
The same tempered glass either way. The only question is whether a standard size already fits your table.
In-Stock Glass Table Tops
Pick your shape and compare the available sizes, glass thickness and prices. If a standard size matches what you need, it is the quickest route to your door.
- Standard sizes ship within 24–48 hours
- Same toughened glass as made-to-measure
- Polished edges on every piece
Custom Cut to Size
For when a standard size does not fit, or the table base needs different measurements or finishing. Give us your dimensions and see the price before you order.
- Cut to the millimetre
- Any thickness from 6mm to 19mm
- Cut-outs, radius corners and centre holes

Replacement Glass for Dining Tables, Coffee Tables, Desks & Patios
Tell us what the glass is for. How it is supported matters as much as its size.
Dining Tables
Replacing a broken top and covering a solid timber table are two different jobs: a replacement has to match the old glass, a cover has to sit neatly over the whole surface. Decide which one you need before choosing dimensions.
Typically 10mm – 12mm toughened
Rectangle Table Tops
Coffee Tables
Oval and round tops suit lounge settings, and a lighter thickness keeps the look open. Measure the widest points if the base tapers, so the glass still clears the frame.
Typically 6mm – 10mm toughened
Oval Table Tops
Desks & Consoles
A cut-to-size cover protects the timber from pen marks, heat and spills while the grain stays visible. Tell us about cable cut-outs or a monitor clamp and we will cut around them.
Typically 6mm – 8mm toughened
Square Table Tops
Patio & Outdoor Tables
Outdoor tops take wind load and temperature swings, so we cut them a little heavier and can drill a centre hole for your umbrella. Edges are polished so the glass stays safe to handle.
Centre umbrella holes available
Round Table Tops
W = width · D = depth · round tops are quoted by diameter
Measure Your Table Top in Six Steps
Every top is cut from the numbers you give us, so a few minutes with a tape measure now saves a re-cut later. Here is exactly what we need.
The measurements we need
- 1
Measure the surface, not the base
Measure the area the glass has to cover. If you are replacing a glass top, measure the old glass exactly — the base underneath is usually slightly smaller.
- 2
Take the width in three places
Measure left to right at the front, the middle and the back. Use the smallest figure you get.
- 3
Take the depth in three places
Measure front to back on the left, in the middle and on the right. Again, use the smallest figure.
- 4
Decide the overhang
If the glass sits on top of a table base, keep the overhang the same all the way round so no part of the base sits proud of the glass.
- 5
Describe your shape
Round: give the diameter. Oval, quarter round, pentagon and triangle: give the overall width and depth across the widest points, plus a radius if the corners are rounded.
- 6
Tell us about cut-outs
Centre holes for umbrellas, cable slots, pop-up sockets or tap cut-outs all change the cut file, so mention them when you send your measurements.
Before you order
- ·Measure in millimetres, never in centimetres or inches.
- ·Use a steel tape measure — a fabric or cloth tape stretches and reads short.
- ·Measure twice. Then check the figures against the drawing we send back before you approve it.
- ·If the base is out of square, give us the smallest width and depth and the glass will still sit flat.

Glass Table Top Buying Guide
Everything you need to order the perfect custom glass table top — from measuring your base to choosing the right thickness, tint and edge finish.
How to Measure
Measure the full width and depth of your table base in millimetres. For a protective cover, add 6–12mm overhang on each edge. Always give us the finished glass size you want, not the base size.
Choosing the Right Thickness
6mm suits decorative covers and small tables. 10mm is the standard for dining and coffee tables. 12mm is recommended for large tops and heavy-use surfaces for rigidity and safety.
Glass Types & Tints
Clear float is the everyday choice. Low-iron gives a crystal-clear, edge-light look. Frosted diffuses light for a soft finish. Bronze and grey tints add warmth or a modern tone.
Edge Finishes
Flat polished is the clean standard. Beveled adds a decorative angled edge. Pencil polished gives a rounded, safe feel for high-traffic tables. Seamed is a cost-effective light finish.
Safety & Tempering
All our table tops are tempered for safety — up to 5× stronger than ordinary glass and breaking into small, safe pieces. Tempering is recommended for any table used by children or in public spaces.
Care & Maintenance
Clean with a soft cloth and glass cleaner. Use coasters and placemats to prevent scratches. Avoid dragging heavy objects across the surface. Re-seal edges annually in coastal areas.
