How Thick Should a Concrete Dining Table Be?
Choosing the right thickness for a concrete dining table affects strength, stability, visual impact and long-term durability.
If you’re considering a polished concrete dining table, thickness is one of the most important — and misunderstood — design decisions.
It doesn’t just affect how your table looks. Thickness directly influences structural strength, visual proportion, leg clearance, stability and long-term durability.
Here’s what you need to know before choosing.
Why Thickness Matters
Concrete is a mineral-based surface system applied over a structural core.
Too thin, and the table can feel lightweight, hollow or flex under load.
Too thick, and the table can overwhelm the room visually.
Getting this balance right is what separates mass-produced concrete tables from true architectural furniture.
Common Thickness Options Explained
30–35mm Profiles
These are slim, lightweight designs typically found in flat-pack or mass-produced ranges. They suit compact spaces but can lack the visual presence and structural depth expected from a premium concrete table.
40–45mm Profiles
A mid-range thickness that offers improved rigidity and presence. These are often used where weight restrictions apply or in smaller apartments.
60–75mm Architectural Profiles
This is the professional standard for large-format, statement dining tables.
Thicker profiles allow for:
• Increased structural rigidity
• Deep, luxurious edge profiles
• Improved stability across long spans
• A premium, architectural appearance
This is the thickness range used for large dining tables, boardroom tables and feature pieces.
Visual Impact
Thicker tables anchor a space.
They feel permanent, confident and substantial — particularly in open-plan kitchens and large dining rooms.
Slim profiles can appear temporary or under-scaled in larger interiors.
Weight & Stability
Thicker tables are heavier and far more resistant to flex and vibration.
Once installed, they feel rock-solid under use.
