How To Choose a House Number Sign
The short version: work through five decisions in order — how far your sign will sit from the road, whether you need a number, a name or both, which material suits your frontage, how it will be fixed, and how it will look after dark. Get the distance right first, because it determines the size, and size determines almost everything else.
A house number sign is a small purchase that gets looked at every single day — by you, by visitors, by couriers and, on the worst day of your life, by an ambulance driver. It is also one of the few things on a house frontage that is genuinely easy to change. This guide walks through the decisions in the order that actually matters, so you do not end up with a beautiful sign that nobody can read.
Start with the distance from the road
Every other decision follows from this one. Stand where a driver would stop — the centre of the road, outside your property — and measure or pace the distance back to the wall, gate pier or door where the sign will go.
As a rough guide, signs within five to ten metres of the road can work with numerals around 75–100mm tall. Between ten and twenty metres, you want 100–150mm. Beyond that, go larger again, or move the sign forward to a gate pier rather than the house itself.
Bear in mind that the sign is larger than the numerals on it. A plaque with 100mm digits and a reasonable margin is typically 150–200mm across. If you are working from a product's overall dimensions, mentally subtract the border before you judge whether the numbers will read.
There is a legal dimension too. UK councils have long-standing powers over street numbering — the Towns Improvement Clauses Act 1847 and the Public Health Act 1925 both bear on it — and the practical expectation is that your number is legible from the public highway. In conservation areas your council may also have a view on materials and style, so it is worth a quick check before you commit to something unusual.
Decide what the sign actually needs to say
There are three common patterns, and they are not interchangeable.
- Number only. The clearest option at distance, and the right choice on most streets. Fewer characters means each one can be larger.
- Number and street name. Useful on long roads, corner plots, or where a development reuses numbers across several closes. The street name can be much smaller than the number — it is read at the gate, not from a car.
- Name, or name and number. Standard for houses with names, and for properties where the name is the postal address. If the number is part of the address, keep it dominant and let the name sit beneath it.
A practical test: write out exactly what you want engraved, then read it aloud as if giving directions. If it takes more than a couple of seconds, it is probably too much for one plaque.
Choose a material that suits the frontage
Material is where personal taste legitimately takes over, but the building should still get a vote. A few principles hold up well:
- Warm materials suit warm brick. Timber and bronze tones sit comfortably against London stock, red brick and stone.
- Cool, flat materials suit rendered and painted walls. Matte acrylic, black and brushed metallics read crisply against white render and pale stucco.
- Contrast matters more than colour. A dark sign on dark brick is a common and expensive mistake. Hold a dark object and a light object against the wall in daylight and see which disappears.
Carvica signs are made from African Iroko hardwood and Perspex® acrylic, usually layered together. Iroko is a dense, naturally oily hardwood used for exterior joinery and boatbuilding; acrylic is dimensionally stable, colour-fast and available in clear, matte, frosted, gloss, pastel, transparent and mirror finishes. We have written a fuller comparison, including materials we do not make, in our guide to house sign materials.
Work out how it will be fixed
This is the decision most people leave until the sign arrives, and it is the one most likely to cause a problem.
There are three broad approaches. Standoffs hold the sign a short distance off the wall, casting a shadow line that adds depth and suits uneven brick. Adhesive fixing, using an industrial tape such as 3M 467MP, avoids drilling altogether but needs a smooth, sound, non-porous surface — render, painted timber, uPVC, glass. Direct screw fixing is the simplest and the least forgiving of error.
Two things to check before you order: whether you are allowed to drill (leaseholders and listed buildings often are not), and what the wall is actually made of. Our guide to fixing a house sign covers each surface in turn.
Think about how it reads after dark
Most house signs are chosen in daylight and then spend half their life in the dark. If your frontage has no lighting, a high-contrast sign — light numerals on a dark ground, or the reverse — will do far more for you than a subtle one. Gloss and mirror finishes pick up whatever light is available, including headlights. Matte finishes stay legible without glare when a porch light is directly above them.
If you are installing a new porch light anyway, aim it so the sign is lit from above or the side rather than head-on, which flattens any 3D lettering.
A quick decision checklist
| Decision | What to consider |
|---|---|
| Distance from road | Under 10m: 75–100mm numerals. 10–20m: 100–150mm. Further: larger, or move it forward. |
| Content | Number only reads best. Add a street name only where it genuinely helps. |
| Material | Warm tones for brick and stone, flat cool tones for render. Prioritise contrast. |
| Fixing | Standoffs for depth and uneven walls, adhesive where you cannot drill, screws for simplicity. |
| Night-time | High contrast beats subtlety. Gloss catches light; matte avoids glare. |
| Position | Roughly eye level, unobstructed by planting, on the side visitors approach from. |
Where personalisation fits in
Because Carvica signs are cut and engraved to order rather than picked from stock, the number, the name and the finish are all chosen at the point of ordering. Production takes five to seven business days, and a designer proof is sent by email before anything is cut — so you see exactly how the spacing and proportion will look on your chosen size before it exists.
That is also the moment to sanity-check the size. Printing the proof at actual size and taping it to the wall for a day is the single most useful thing you can do before committing.
Common questions
Should the sign go on the house or the gate?
Whichever the visitor sees first. If the house is set well back, or hedging obscures the frontage, a gate pier is usually the better position — and it lets you use a smaller sign than the distance would otherwise demand.
Do I need both a number and the street name?
Only where the road is long, the numbering is confusing, or you are on a corner. On a typical residential street, the number alone is clearer.
What if my wall is very uneven?
Standoff fixings are the usual answer. They bridge irregular brick and stone far better than flush mounting, and the shadow gap disguises any slight variation behind the sign.
How long does a made-to-order sign take?
At Carvica, production runs five to seven business days from order, with free worldwide shipping on top. A designer proof is sent before production begins.
When you are ready to look at designs, our house number signs and address plaques are made to order in Iroko hardwood and Perspex acrylic, in sizes from 120mm up to 300mm.
