Why Accuracy Matters
A custom glass table top should fit like a glove—aligned with your table frame, safe for use, and visually seamless. Even a few millimetres off can lead to wobbles, sharp edges, or costly reorders. Inaccurate measurement can compromise safety and aesthetics.
This guide lays out a foolproof method—from selecting the right glass type and edge profile to measuring precisely, coordinating shipping, and installing properly. Whether you’re an interior designer working with clients or a homeowner tackling a DIY upgrade, these tips will help you get it right the first time.
Choosing the Right Glass Type & Thickness
Tempered vs. Annealed Glass
Tempered glass is heat-treated for safety; it shatters into small nuggets rather than sharp shards—ideal for family environments.
Annealed glass is less expensive but breaks into large, jagged fragments—suitable for low-risk areas or where cost is paramount.
Thickness Options
6 mm: Great for small end tables or desks; provides sleek, lightweight appeal.
10 mm: A balanced choice for mid-size dining or console tables—sturdy and elegant.
12 mm: Preferred for larger tables (up to 120 cm width), offering superior support and weight capacity.
Thicker glass improves stability and reduces the feel of flex, but costs and shipping weight go up—balance with table size and usage.
Selecting Edge Profiles & Finishes
Edging affects safety, style, and installation ease:
Pencil-Round: Smooth, rounded edges that resist chipping—subtle and safe.
Beveled: Angled edges offer a decorative touch; adds visual depth.
Polished: Clean, crystal-clear edges that highlight thickness—ideal for modern tables.
Seamed (Raw): Economical, but sharp and prone to chipping—least recommended.
For families or high-use settings, pencil-round or polished edges are safest—they both offer durability and comfort. Bevels add elegance but can be trickier to install evenly.
Measuring Correctly: Tools & Techniques
What You’ll Need
Steel tape (for accuracy), digital caliper or level (for thickness checks)
Paper/pen, masking tape, rubber bumpers
Step-by-Step Instructions
Measure length and width twice, rounding down to the nearest millimetre for safe margins.
Determine overhang or inset—standard: 10–20 mm overhang provides visual balance without overhang risks.
Mark clearly on masking tape rather than writing directly on the table surface.
Check diagonals—measure corner to corner both ways; they should be equal (or within 1 mm difference).
Confirm before ordering—having a second person cross-check prevents costly errors.
Record final dimensions: length × width × thickness, edge style, and any hole cutouts (e.g., umbrella hole).

Packaging & Shipping Tips for Glass
Glass requires expert handling—ensure your supplier ships it safely:
Wooden crate with internal foam framing prevents shifting and shocks.
Edge protection using rubber or foam corner caps reduces chipping risk.
Anti-scratch poly film on both sides preserves glass clarity.
Handling labels like “Fragile” or “This Side Up” ensure carrier awareness.
LTL shipping with tracking—choose insured delivery.
Upon arrival, inspect before signing:
Check for chips, cracks, or scratches and compare dimensions with your record.
Take photos of any shipping damage or packaging issues in case of claims.
For expert precision, trust a dedicated custom glass company to handle all cutting, edge finishing, and secure delivery for your perfect-fit tabletop.
Installation Checklist
Prepare your frame—ensure it’s level using a spirit level; uneven frames can stress the glass.
Add rubber bumpers to support edges and prevent slippage or scratches.
Lower the glass gently—start with one side, rotate carefully, and avoid sliding.
Maintain overhang safety—don’t exceed manufacturer-recommended margins, especially on thicker glass.
Clean using a glass-safe cleaner and lint-free cloth—avoid harsh chemicals that degrade edges.
FAQ – Measuring & Installing Custom Glass Table Tops
Can I install a 12 mm glass top on a small coffee table?
Yes—12 mm offers solid feel and stability up to about 120 cm. For larger tables, consider 15 mm to prevent flex.
Is tempered glass necessary for home use?
Highly recommended—it’s safer for households since tempered glass breaks into less dangerous pieces.
How much overhang is acceptable?
Typically 10–20 mm. Always check supplier specs—larger overhangs may necessitate thicker glass or extra support.
Do polished edges prevent chipping?
Yes—edge polishing removes tiny fractures that can become chips under stress.
What if my delivery arrives damaged?
Wilt for inspection before opening. If you refuse shipment due to visible damage, retain photos and documentation for freight claims.
Conclusion: Measure with Confidence
Measuring for a custom glass table top is straightforward when you have the right tools and steps. From choosing the right glass type and edge finish to taking precise measurements, coordinating delivery, and installing carefully—you’ll achieve a flawless result.
By measuring accurately, confirming details, and working with trusted suppliers, your custom glass top will elevate any space—safe, stylish, and seamless.
