Tempered Glass Cut to Size: How Ordering Works, Step by Step
Anyone searching for tempered glass cut to size soon learns an awkward rule: the cutting is done first, and the glass cannot be touched afterwards. This guide in our tempered glass series explains the sequence, the choices you make along the way and the details we need from you.
Quick answer
Short answer: no, tempered glass cannot be cut, drilled, notched or edge-ground once it has been tempered. The pane is made to your exact size in a fixed order: measure, cut, finish the edges, make holes and notches, then temper and install. So the work that matters most happens before production, in the measuring and in the specification.
Can tempered glass be cut? Why the answer is no
A tempered pane holds a strong balance of stress between its surface and its core. Any attempt to cut, drill, grind or even deeply scratch the edge breaks that balance, and the whole sheet fails. That is why you cannot buy a large tempered sheet and trim it to your table at home, however good your tools are.
It also means there is no "fixing it on site". If the pane turns out a little long, a little short or without a hole you needed, the pane is not adjusted. A new one is made. Everything in this guide follows from that one fact: the size and every feature must be final before the glass goes into the furnace.
The order of work, from tape measure to installation
The sequence is always the same. Knowing it helps you see which decisions are yours and when they stop being changeable.
Measure. The opening, table frame or wall space is measured and the sizes are written down with the pane's intended position.
Confirm the specification. Thickness, clear or tinted, edge finish, corner shape, holes, notches and hardware are agreed.
Cut. Plain glass is cut to the agreed size and shape.
Edge. The edges are ground and polished to the agreed finish.
Holes and notches. Any drilling, cut-outs or notches are made now, never later.
Temper. The finished pane is heated and cooled rapidly. From here nothing changes.
Check and install. The pane is inspected, delivered and fitted with the right hardware or supports.
Steps three to five are the ones people assume can be redone. They cannot, which is why the specification in step two deserves your full attention.
Edge finishes explained
A raw cut edge of glass is sharp and rough, so every tempered pane has its edges worked before treatment. The finish changes the look, the feel and sometimes the price, and it should match how visible the edge will be.
| Edge finish | How it looks and feels | Where it is typically chosen |
|---|---|---|
| Arrised (seamed) | Sharp corner softened, matte, plain look | Edges hidden inside a frame or channel |
| Flat polished | Smooth, glossy, square edge | Table tops, shelves, doors with visible edges |
| Rounded or pencil | Soft curved edge, comfortable to touch | Table tops, desks, counters where hands pass |
| Bevelled | Angled decorative edge that catches light | Mirrors, decorative panels |
| Shaped or contoured | Custom profile following a curve | Special-shaped table tops and feature panels |
Ask us which finishes can be made for your shape and use. Not every finish suits every thickness or every outline, and we confirm what is possible when we see the details.
Holes, notches and cut-outs
Hinges, handles, wall fixings, rails, sockets and pipe positions often need openings in the glass. These are made before tempering, at positions measured from the edges of the finished pane, not from the wall or from a picture of the hardware.
The general principle is that glass dislikes weakness near its edges and corners. Holes work best at sensible distances from the edge and from each other, and notches should have gently rounded inner corners rather than sharp ones. The exact limits depend on size, thickness and the hardware chosen, so we do not guess here. If your design needs several openings, send the hardware or its data sheet with your request so the positions can be checked before production.
Corner shapes
A tempered pane does not have to have square corners. Slightly rounded corners are popular for table tops, since they are friendlier to hips and children's heads and also reduce the risk of corner chips. Larger radii give a softer, more modern outline, and cut-off corners suit certain frames.
Square corners are still the usual choice for panels set into frames, because the frame hides them. If the glass will be handled often or sit where people brush past it, choose corners and edges with that in mind. Whatever you choose, say so in the order, because changing it later means a new pane.
How to give dimensions clearly
Write sizes as width × height (or length × width for a flat top) and always state what they refer to: the opening, the frame, or the glass itself. The most common mistake is giving the opening size when you actually need the glass size, which is smaller to allow for movement and fixing. Tell us which one you measured and we will convert it as part of confirming the order.
A quick sketch helps more than a long message. Draw the shape, mark each side with its size, mark the position of any hole or notch from two edges, and mark which face is the front. Use one unit throughout and write it next to the figures. A photo of the sketch together with a photo of the place is an excellent start, and we verify everything before cutting.
The measuring mindset
Measuring for glass rewards patience more than skill. Measure each dimension in more than one place, because walls, frames and floors are rarely perfectly straight and the smallest figure is usually the one that matters. Check whether corners are square, and note any bulge, step or slope.
Write the figures as soon as you take them, not from memory. Put the measurement of the supporting frame or base next to the glass size so the difference is visible. And if a dimension is unclear, leave it as "unsure" instead of rounding it. For a shower area, which has its own particular points to check, our shower measurement guide covers the details. This page keeps to general items such as tables, mirrors, panels and doors.
Irregular shapes: make a template
Curved table tops, angled walls, odd alcoves and shaped shelves are difficult to describe in numbers. The reliable answer is a template. Cardboard, thick paper or thin foam board cut to fit the space gives an exact outline that can be transferred directly.
Cut the template slightly small, test it in place, then trim until it sits correctly. Mark the front, the top edge and the position of holes, and write the date and the item name on it. Photograph it in place and, if possible, with a tape measure across it. We can then work from the template, check it against your sizes and confirm the shape before anything is cut.
What to think about for each kind of item
| Item | Details that must be decided before cutting | Common slip |
|---|---|---|
| Table top | Outline, corner radius, edge finish, support positions, whether anything hot will sit on it | Measuring the old top, which has worn or been adjusted |
| Shelf | Length, depth, bracket type and spacing, edge visible or hidden | Ignoring how the bracket grips the glass |
| Mirror or panel | Fixing method, holes for fixings, edge finish, backing | Choosing holes after the glass is made |
| Door leaf | Hinge or patch fitting positions, handle holes, lock cut-outs, clearances | Not checking the frame for squareness |
| Wall panel or partition | Overall size, joints between panes, channel or clip details | Giving the wall size without allowing for fixings |
For special cases see custom mirrors, glass doors and glass partitions. Some items, like table tops, shelves and kitchen panels, have their own pages in this series, including one on tempered glass table tops and shelves.
What we ask you when you contact us
Send what you have through the contact page, even if it is incomplete. We work with photos, rough sizes and a short description, then we confirm everything by measuring where needed. The questions you can expect are:
What is the item and where will it go indoors or outdoors?
What are the sizes, and are they of the opening, the frame or the glass?
Clear glass, tinted, frosted or something else?
Which edge finish and corner shape do you prefer?
Are holes, notches or cut-outs needed, and what hardware will be used?
Will anything hot, heavy or sharp touch the glass?
Who will install it, and is access to the site straightforward?
Our service area is Taif. If you are searching for tempered glass cut to size near me, that is where we measure, quote and install.
What affects how long an order takes
We cannot give a general timeframe here, because it depends on the order. The things that shape it are the number and size of panes, how complex the shape is, how many holes and notches are needed, whether a special finish or tint is involved, and how quickly the specification is settled. Unclear measurements and changes after production begins are the biggest source of delay, and they usually mean making the pane again. When you ask us, we confirm the timing for your order once we know these details.
Ordering mistakes worth avoiding
| Mistake | What happens | How to avoid it |
|---|---|---|
| Ordering from the opening size | Glass too big to fit or loose in the opening | State what you measured and let us confirm the glass size |
| Deciding on holes later | A new pane is needed | Choose hardware first and send its details |
| Using a worn old top as the pattern | New glass copies the old errors | Measure the frame or support, not just the old glass |
| Mixing units in one message | Misread sizes | Use one unit and write it down |
| Rounding to a neat figure | Gaps or tight fit | Give the real figures and let us advise |
| Changing the spec after cutting | Wasted pane, repeated work | Settle thickness, edge and finish before approval |
| Ignoring how it will be fixed | Hardware that does not match the glass | Mention the fixing method at the start |

Frequently asked questions
Can tempered glass be cut?
No. Once glass has been tempered, it cannot be cut, drilled, notched or ground without breaking. All cutting, edging and drilling must be done before the tempering process.
Can I order tempered glass cut to size for a table top?
Yes. The top is made to your measured size, with the chosen edge finish and corner shape. Send us a sketch, photos and the frame sizes, and we confirm the details before production.
What is the difference between cut to size and ready-made?
Cut to size means the pane is made to your measurements. A ready-made item is a fixed standard size. For a particular opening or frame, a made-to-measure pane is the dependable route.
Can holes be added to tempered glass later?
No. Holes, notches and cut-outs must be specified before tempering. If you change your mind afterwards, a new pane has to be made.
What if my shape is not a rectangle?
Make a template from cardboard or thick paper that fits the space, mark the front and any holes, then photograph it in place and send it to us. We check it before cutting.
Should I give the size of the opening or the glass?
Either works as long as you say which one it is. Opening sizes need an allowance for fitting and movement, and we calculate the glass size when we confirm the order.
