Why Order Custom Cut Tempered Glass?
Most glass installations are not one-size-fits-all. You need custom cut glass when:
- Your space has non-standard dimensions
- You are replacing broken pieces
- You are installing glass in curved or angled structures—projects that typically require following a specific tempered glass installation guide to ensure a safe and precise fit.
Custom tempered glass ensures a tailored fit for:
- Shower enclosures
- Office partitions
- Shelving
- Tabletops
- Balcony railings
- Windows and doors
Ordering tempered glass panels that are custom-cut minimizes gaps, improves aesthetics, and improves structural safety.

How to Measure for Custom Cut Glass
Tools You Will Need
To ensure accuracy, gather:
- Metal measuring tape (not fabric)
- Straight edge or level
- Pencil or fine marker
- Notepad or template sketch
- Laser measurer (optional for precise measurements)
Step-by-Step Measuring Guide
a. Measure Width and Height
- Always measure to the nearest 1/16 inch.
- Measure at three points, top, middle, bottom and use the smallest value.
b. Record Orientation
Mark clearly which side is the top/bottom if shapes aren’t symmetrical.
c. Account for Gaps
- For framed installations, subtract 1/8″ from each dimension.
- For frameless glass (e.g., tabletops), use exact dimensions.
d. For Irregular Shapes
- Create a cardboard or paper template
- Label reference points and corner radius measurements
Common Measurement Mistakes to Avoid
- Measuring from wrong surfaces (e.g., drywall instead of studs)
- Rounding up measurements
- Forgetting to subtract for frame clearance
- Ignoring hardware or mounting allowances
Choosing Your Glass Specifications
Glass Thickness Options
| Use Case | Recommended Thickness |
| Cabinet doors | 1/8″ |
| Picture frames | 1/8″ or less |
| Shelves | 3/16″ – 3/8″ |
| Table tops | 1/4″ – 1/2″ |
| Shower doors | 3/8″ – 1/2″ |
| Partitions | 1/4″ – 1/2″ |
Thicker tempered glass sheets provide more strength, but also more weight. Consult with your installer or vendor before finalizing.
Edge Finishing Options
Edge treatments improve both safety and appearance:
- Seamed Edge: Standard safety finish with no polish
- Flat Polished Edge: Modern look for table tops
- Beveled Edge: Angled edge for a decorative profile
- Pencil Polished Edge: Smooth, rounded edges
Hole Cutouts and Corner Options
- Drilled Holes: Needed for hinges or knobs
- Radius Corners: Prevent chipping, especially for glass tables
- Notches and Cutouts: For mounting over outlets or handles
Always include exact placement measurements when ordering.
