How Big Should My Sign Be? A Complete Guide to Choosing the Right Size
Introduction
One of the most common questions clients ask when planning signage is: “How big should my sign be?” Whether it’s a reception sign, a hallway plaque, or wall branding, the right size can make or break its impact. A sign that’s too small gets ignored — too big, and it may overwhelm. At Lumivas Signs, we help Toronto-based businesses find that perfect balance of visibility, proportion, and cost-efficiency. In this article, we break down the key factors to consider when sizing your sign to ensure it delivers the look, message, and durability you need — without overspending.
Assessing Wall Dimensions and Space
Before diving into sign designs, it’s essential to gather the basic dimensions of your wall and the environment around it. Measure the Wall Width and Height

Sign Width Rule of Thumb
A sign typically looks best when it takes up 50% to 75% of the wall’s width. The sign’s height should be proportionate to the wall height, ensuring it fits comfortably without looking cramped or dwarfed by empty space.


Quick Chart for Sign Sizing
Here is a quick reference table that combines wall width with a recommended sign range:
Consider that these dimensions are guidelines. Depending on your brand’s aesthetic, logo complexity, and space usage, you may choose a size slightly smaller or larger than the general recommendations.

Viewing Distance and Legibility
How far away will visitors typically stand when reading your sign? That distance plays a major role in sizing—particularly for your lettering.
The chart below offers general guidelines for Recommended Letter Height based on how far away a person is likely to be from the sign.

Other Considerations
Obstructions: If placing the sign on a wall with furniture, artwork, or other elements, consider a slightly smaller size to maintain balance.
Ceiling Height: Higher ceilings allow for larger, taller signs without overwhelming the space.
Logo Complexity: If the logo has intricate details, a slightly larger size helps maintain clarity.
Letter Visibility: Avoid making letters too small, as readability diminishes at a distance.
Conclusion
Choosing the right lobby sign size is all about balancing aesthetics with practical visibility. By measuring your wall space, considering how visitors interact with the area, and accounting for design complexity, you can create a stunning sign that leaves a lasting impression.
