Stone Benchtop Edge Profile Guide
The edge profile is one of the most overlooked decisions in a stone benchtop project, but it has a real effect on how the benchtop looks, feels and holds up over time. This guide compares the eight edge profiles TN Stone fabricates most often, explains which profile suits porcelain, marble, granite and quartz, and covers 20mm vs 40mm benchtops, cost tiers and care.
Key takeaways
- Pencil round is the safest default, especially for porcelain, because rounded edges resist chipping better than square corners.
- Granite and quartz are durable enough to suit almost any profile, including square edge.
- Marble benefits from a softer profile such as bullnose, since it chips more easily at sharp corners.
- Mitred 40mm gives a 20mm slab the look of a substantial 40mm benchtop without the extra material cost and weight.
8 stone benchtop edge profiles
Pencil round
Recommended standard
A subtle, rounded edge with a small radius. Comfortable to the touch and the most chip-resistant profile available, which is why it is our default recommendation for kitchen and bathroom benchtops in any material, including porcelain.
Arris (eased edge)
Subtle, low-chip
A very light chamfer that softens a square corner without changing the look of the benchtop. A good low-cost alternative to pencil round where a crisper, more architectural line is preferred.
Square edge
Clean, modern
A sharp 90-degree corner for a clean, contemporary look. Suits granite, quartz and other durable materials well. Not recommended for porcelain, where sharp corners are more prone to chipping.
Bevelled edge
Angled facet
A flat, angled facet cut into the top edge. Adds a defined line of light and shadow along the benchtop and works well on both natural stone and engineered stone.
Half bullnose
Curved, soft
A quarter-round curve softens the top of the edge while the underside stays square. A popular middle ground between a square edge and a fully rounded bullnose.
Full bullnose
Fully rounded
The entire edge thickness is rounded into a smooth D-shape. Comfortable, family-friendly and forgiving on softer stones such as marble, where sharp edges are more vulnerable to chipping.
Shark nose
Sharp, tapered
A flat top edge that tapers to a fine point on the underside, giving a slim, sharp profile. A striking, contemporary look, best suited to durable materials such as granite and quartz.
Mitred 40mm
Doubled thickness look
Two 20mm slabs are mitred together to create the appearance of a solid 40mm benchtop, without the extra material cost and weight of a true 40mm slab. A popular way to get a substantial, high-end look on islands.
Which edge profile suits your stone?
Porcelain
Pencil round or arris. Avoid square edge — porcelain is the most chip-prone material at sharp corners.
Marble
Half or full bullnose, or a bevelled edge. Marble is relatively soft, and a softer profile protects the edge.
Granite
Durable enough for any profile, including square edge and shark nose.
Quartz
Suits most profiles. Mitred 40mm is a popular choice for a bold, substantial island edge.
20mm vs 40mm benchtops
20mm slabs read lighter and suit contemporary kitchens at a lower material cost. A true solid 40mm slab is heavier and more expensive to fabricate and install. Most fabricators, including TN Stone, achieve the same substantial look for less by mitring two 20mm pieces together at the front edge (mitred 40mm), which is virtually indistinguishable once installed.
Cost guide: standard, premium and custom edges
Edge profile pricing generally falls into three tiers:
Standard profiles are included in most benchtop quotes at no extra cost. Premium profiles involve a moderate upgrade for the additional shaping and polishing time. Custom profiles such as shark nose and mitred 40mm are priced per project, since they take longer to fabricate.
Caring for your benchtop edge
Rounded profiles such as pencil round and bullnose are the easiest to keep clean and the most forgiving of daily knocks. Sharper profiles such as square edge and shark nose look striking but show chips more readily, particularly in softer materials. Avoid placing heavy pots or appliances directly on the edge, and always use a chopping board rather than cutting directly on any stone surface.

What is the best edge profile for a porcelain benchtop?
Pencil round or arris are the safest choices for porcelain. Both minimise the amount of exposed sharp corner, which is where porcelain is most likely to chip.
Does a 40mm benchtop always mean a solid 40mm slab?
Not usually. Most 40mm-look benchtops, including ours, are mitred from two 20mm pieces joined at the front edge. This achieves the same appearance as a solid 40mm slab at a lower material cost and weight.
Which edge profile is easiest to clean?
Rounded profiles such as pencil round and bullnose have no sharp corners to trap crumbs or grout, and are the easiest to wipe down.
Can I mix edge profiles on the same benchtop?
Yes. Some clients choose a bullnose on an island for a softer, family-friendly edge, and a square or bevelled edge on perimeter benchtops for a more architectural look.
