Custom Glass Cutting: When Standard Sizes Won't Work

Sometimes you need glass in exact dimensions—a tabletop that fits perfectly, shelves for a specific alcove, or replacement glass for a unique piece of furniture. Here's how custom glass cutting works and what to bring when you need a specific size.

Common Custom Glass Applications

Table tops: Protecting wood, stone, or painted surfaces while adding elegance. Glass tops also make cleaning easier and prevent scratches.

Shelving: Custom shelves for built-ins, display cases, or unique storage solutions. Glass shelves admit light and feel less heavy than solid alternatives.

Cabinet doors: Replacement glass for china cabinets, curio cases, or kitchen cabinets. Can match existing style or update the look.

Desk protectors: Custom-sized glass for desks and workstations.

Picture frame glass: Non-standard sizes for custom framing projects.

Replacement panes: Matching glass for furniture, windows, or doors when standard sizes don't fit.

What to Measure (and How)

Accurate measurements are essential—glass can't be trimmed after cutting like wood can.

For table tops: Measure the surface you're covering. Decide if you want the glass flush with edges or slightly smaller (1/8" per side is common to prevent overhang chips).

For shelves in cabinets: Measure the opening width at front, back, and middle—openings aren't always square. Use the smallest dimension and subtract 1/8" for clearance.

For replacement glass: Bring the old piece if possible, or make a template from cardboard for unusual shapes.

When in doubt, bring the item itself. We'd rather measure a cabinet door in the shop than cut glass that doesn't fit.

Glass Types for Different Uses

Standard clear glass: Economical choice for picture frames, small shelves, and protected applications.

Tempered glass: Heat-treated for strength and safety. Required for table tops, shelves with significant spans, and anywhere people might impact the glass. Shatters into small pieces if broken rather than dangerous shards.

Laminated glass: Two pieces bonded with plastic interlayer. Stays together if broken. Good for table tops that might see heavy use.

Low-iron glass: Ultra-clear glass without the green tint of standard glass. Best for displaying items where color accuracy matters.

We'll recommend the appropriate type based on your application.

Edge Finishing Options

Raw-cut glass edges are sharp. All custom pieces should have finished edges:

Seamed: Basic finish that removes sharpness. Edges aren't polished but are safe to handle. Most economical option.

Flat polished: Smooth, shiny edges. Professional appearance for visible edges. Standard for table tops and shelves.

Pencil polished: Slightly rounded, polished edge. Softer look than flat polish.

Beveled: Angled edge that catches light attractively. Premium option for decorative applications. Typically 1" wide bevel.

Thickness Guidelines

3mm (1/8"): Picture frames, small cabinet inserts

5mm (3/16"): Small table tops (under 24"), short shelves

6mm (1/4"): Medium table tops, standard shelving

10mm (3/8"): Large table tops, longer shelf spans

12mm (1/2"): Heavy-duty table tops, large unsupported spans

Turnaround Time

Standard rectangular cuts with basic edges: Often same-day or next-day

Tempered glass: 3-5 business days (requires outside processing)

Complex shapes or special finishes: 1-2 weeks depending on complexity

What to Bring

Precise measurements (double-check before you come)
