House Number 15 cm | The ideal size for any house wall

For whom is a 15 cm house number the right choice?

A house number 15 cm high is clearly legible at a distance of up to 15 meters between the front door and the street. This corresponds to the typical distance for a single-family house with a front garden. The 15 cm variant appears proportionate and not too dominant on an average-sized facade. It is available in most of our series, both as a drilled version and without drilling, and in all colors from black to stainless steel to gold and white.

When is 15 cm the right size?

The choice of the correct house number size primarily depends on the distance between the house number and the street. As a rule of thumb: for every 10 meters of distance, the height of the house number should be at least 10 cm. For a distance of 10 to 15 meters, the 15 cm version is the optimal choice. It is clearly legible from this distance and at the same time appears proportional to the facade. For houses located directly on the sidewalk, the 10 cm version is often sufficient. For houses with more than 20 meters distance from the street, we recommend the 20 cm or 30 cm version.

15 cm with and without drilling

Our 15 cm house numbers are available in two mounting options. The drilled models are attached to the facade with screws, anchors, and spacers and stand slightly off the wall, creating a clean shadow. The self-adhesive versions adhere permanently to smooth surfaces such as painted metal, smooth plaster, or mailboxes with a high-quality adhesive solution. Both versions are weather-resistant and designed for permanent outdoor use.

Frequently Asked Questions about 15 cm House Numbers

Is 15 cm large enough for a busy street?

For a busy street where cars pass at higher speeds, we recommend at least 15 cm, preferably 20 cm. The faster the traffic, the shorter the time a house number can be perceived. A 15 cm house number is well suited for quiet residential streets and sidewalk locations. On busy streets with more than 15 meters distance to the roadside, the 20 cm version is the safer choice.

In what colors is the 15 cm house number available?

The 15 cm house number is available in our range in black, white, gold, and stainless steel. Not all series can be combined in every color and size. On this page, select the desired color using the filter options or visit the respective color collection page for a complete overview of available models.

Can I also attach a 15 cm house number to my mailbox?

Yes, with the self-adhesive version. The 15 cm models without drilling are well suited for larger mailboxes or fence posts made of metal or painted material. For smaller mailboxes, we recommend the 7.6 cm or 5 cm version, as these are proportionally better suited to standard mailbox formats.
