Why house numbers matter more than most homeowners realise
House numbers aren't just decorative. Poorly visible or missing numbers cause missed or delayed deliveries, confusion for visitors, slower response times for emergency services, and frustration in estates and complexes. A well-chosen house number solves these problems while improving how the property looks.
What size house number do I need?
Numbers should be at least 100–150mm tall for a property set 5–15 metres back from the pavement, and 200mm or taller for anything set further back — the same principle applies whether you're mounting individual digits or a full panel design. If you're unsure, go bigger: an oversized number is far less common a complaint than one nobody can read from the road.
Best materials for house numbers in South Africa
Powder-coated mild steel
The most common and cost-effective finish for outdoor house numbers. It resists UV fading and moderate moisture with minimal upkeep, and it's the standard finish across Art on Steel's range, in black or white.
Brushed stainless steel
Available on Art on Steel's Modern and Bold digit line, brushed stainless holds its finish for years without repainting and resists salt air better than mild steel. It's the better choice for coastal properties, or anywhere long-term, maintenance-free finish matters more than upfront cost.
Coastal and high-humidity areas
If you're near the coast or in a humid region, material choice matters more. Choose brushed stainless steel where it's available, or a powder-coated finish over untreated metal, and rinse occasionally to remove salt buildup. With the right material, a house number can last for years even close to the ocean.
How should house numbers be mounted?
Three mounting approaches cover most South African homes:
- Flush screw mounting — the most secure method, suited to both face brick and plastered masonry. On face brick, drill into the brick itself rather than the mortar joint. On plaster, anchor into the masonry behind it, not the plaster alone.
- Floating spacer mounting — numbers stand slightly proud of the wall on standoffs, creating a shadow effect that improves visibility and suits modern homes.
- Mounting tape — fine for lightweight indoor pieces, but not a substitute for mechanical fixing on an outdoor, weather-exposed house number.
All mounting screws and plugs are included with Art on Steel house numbers, so there's no separate hardware to source.
Estate and complex requirements
Many estates and complexes have rules around minimum number size, approved colours, and consistent styling across units. Always check your estate's guidelines before ordering to avoid a costly replacement.
Placement tips for best results
Install at eye level or slightly above, make sure the number is visible from the street rather than hidden behind gates or plants, and add lighting if visibility at night is poor. Even a well-designed number fails if it's poorly positioned.
Common mistakes to avoid
- Choosing a number that's too small for the viewing distance
- Prioritising decoration over readability
- Ignoring coastal exposure when choosing a finish
- Mounting the number somewhere it's obstructed
Is this made to order?
Yes — every house number is cut, personalised, and finished to order rather than kept in stock. Standard designs typically take around 2 weeks in production; custom or personalised designs can take up to 6 weeks, since dispatch is gated on drawing approval.
What does shipping cost?
Shipping is free on orders over R2,000. Below that, it's R140 within Gauteng or R160 elsewhere in South Africa.
FAQ – Custom House Numbers South Africa
What size house numbers are best for visibility?
At least 100–150mm for properties close to the street, and 200mm or taller for anything set further back.
What material is best for outdoor house numbers?
Powder-coated mild steel for most inland homes; brushed stainless steel for coastal properties or where a maintenance-free finish matters most.
Will metal house numbers rust near the coast?
Standard powder-coated mild steel is more exposed to salt-air corrosion than brushed stainless, which is the better choice for coastal installations.
Are floating house numbers better?
Floating mounts improve visibility with a shadow effect and are popular for modern homes, though flush mounting is the more secure option overall.
Do estates have rules about house numbers?
Many do — they can specify size, colour, and style. Always confirm requirements before ordering.
