Business Sign Size Guide: Choosing the Right Dimensions for Your Sign
Choosing the right size for your business sign helps ensure it is visible, readable, and proportionate to your storefront or building.
A sign that is too small may be difficult for customers to see from a distance, while an oversized sign may not fit the space or look balanced on your building.
This guide explains common business sign sizes and basic visibility guidelines to help you choose the right dimensions for your storefront sign, outdoor building sign, or interior logo sign.
If you're unsure what size sign is best for your location, our team can help recommend the ideal dimensions based on your space and viewing distance.
Storefront Sign Size Guide
Storefront signs are typically mounted above an entrance, on a facade, or inside a window. The ideal size depends on the width of the storefront and how far away customers will view the sign.
Common storefront sign sizes include:
- 24" × 12" – small storefronts or window signage
- 36" × 24" – a common wall-mounted business sign size
- 48" × 24" – larger storefronts or signs designed for increased visibility
For most small to medium retail storefronts, a sign between 36" and 48" wide provides a good balance of visibility and proportion.
Outdoor Building Sign Sizes
Exterior building signs are often larger than storefront signs because they must be visible from greater distances such as parking lots or nearby roads.
Typical outdoor business sign sizes include:
- 48" × 36" – common exterior wall sign
- 60" × 36" – larger storefronts or building signage
- 96" × 48" – large building signs designed for maximum visibility
Many custom signs are produced as Dibond aluminum composite panels, which are durable, weather-resistant, and lightweight for outdoor installations.
Businesses installing outdoor business signs often require larger lettering to ensure visibility from passing traffic.
Restaurant Menu Board Sizes
Menu boards are designed to clearly display menu items and pricing while remaining easy to read from a counter or ordering area.
Common restaurant menu board sizes include:
- 24" × 36" – compact menus for small spaces
- 36" × 48" – medium sized menus with additional items
- 48" × 96" – large restaurant or concession stand menu displays
Menu boards are often produced using durable printed materials such as PVC panels or aluminum composite signs, making them long-lasting and easy to mount.
Sign Letter Height and Viewing Distance
In addition to the overall sign size, the height of the lettering plays a major role in readability.
A commonly used guideline in signage design is:
1 inch of letter height for every 10 feet of viewing distance
Examples:
- 3-inch letters – readable from approximately 30 feet
- 6-inch letters – readable from approximately 60 feet
- 10-inch letters – readable from approximately 100 feet
Larger lettering improves visibility, especially for roadside signs or businesses located in busy commercial areas.
How to Choose the Right Sign Size
When selecting the dimensions for a custom business sign, consider the following factors:
Viewing distance
How far away customers will be when they first see the sign.
Wall or installation space
The size of the wall or mounting area available for the sign.
Traffic speed
Signs near roads or parking areas may require larger lettering for quick visibility.
Design layout
Logos with more text or detailed graphics may require a larger sign to maintain readability.
