Selecting the right size for your sign board will help you to gain visibility, save money, and ease up the installation. When you want to advertise anything from real estate, office, road, to retail sign boards, then knowing the sizes of sign boards will definitely be very useful. This article provides information on standard sizes of sign boards.
1. Why Is Sign Board Size Important?
The size of the sign board you select impacts your ability to communicate your message. Smaller boards may be hard to read at a distance, while an oversized board will result in increased material cost, increased transportation cost, and problems during installation.

When selecting the size for your business needs, it will help you maximize material utilization and optimize production process.
- Visibility:Larger boards provide more surface for you to place your message, logo, image and directional information. For roadside advertisement, you need larger dimensions than for indoor office sign.
- Material Utilization:With standardized sheet size, you can cut multiple boards from a parent sheet; it will help you save on material.
- Transportation and Storage:The standardized dimensions will make it easier to package and store your signs. Bigger finished boards might require special packages to prevent their bending or breakage along the edges.
- Installation:Sign board size should match the mounting system. The smaller boards are usually mounted on brackets or stakes while large outdoor panels will require more robust frames.
Not always the biggest possible size will be the most suitable one for your business. It is recommended to select the right dimensions based on the requirements and minimize production, transportation and installation costs.
2. Standard Sizes for Sign Boards

3. What are the Factors to Consider when Selecting the Sign Board Dimensions?
Before choosing the size of your sign boards, consider the following factors:
- Distance from viewer:If the viewer is farther away from the sign, then you would need more space for larger lettering. A standard rule of thumb that is often applied is 1 inch of letter height for 10 feet of viewing distance. This depends on your font style, color contrast, and light conditions.
- Availability of installation space:First measure your available space to determine the size of the board you will need. A big board will not fit into a narrow walkway or a small retail window.
- Message Length:A short message is advisable for smaller signboards. If you have to convey a lengthy message, more elaborate instructions, and additional contact details, then bigger signboards will be required. Pay attention to your headings.
- Printing and Cutting Efficiency:Think about the size of your printer’s work area and the size of the parent sheet. A 1,220 × 2,440 mm sheet might suit you for printing various sign sizes, based on your cutting layout and allowance.
- Environment:Signs placed outside might face exposure to wind, rain, sunlight, and temperature variations. The larger the panel, the greater the wind load; therefore, you need to consider the strength of your board, the thickness, the spacing of the supports, and mounting hardware.
- Transport costs:It is best that you take into consideration the transport costs when you import either the full sheets or pre-cut boards. For example, the transport cost for 100 full sheets will be $350 while that of the pre-cut boards will be $250. You need to add packaging costs, in order to calculate your most cost-effective alternative.
- Local regulations:There may be some local restrictions regarding the size or placement of your sign boards or advertisement itself. For example, you might need to apply for a permit to install your signboard, along with size limitations and particular distances from roads or intersections where your signs will be posted. Limitations may also apply to sign lighting, temporary banners, and even signs in residential areas. It is important for you to be aware of sign regulations in your area before you place an order.

6. Frequently Asked Questions FAQs
Q1. Can PP corrugated boards be used for billboards?
PP corrugated boards may be used for some of your lightweight promotional panels. But for large billboards, special materials that match the size and installation environment need to be used.
Q2. Do you have to buy thicker material when requesting a bigger sign board?
Yes, otherwise, the board will bend. The small yard signs use thin 4mm corrugated plastic whereas 8ft wall boards need 3mm thick aluminum composite material to withstand strong winds and not bend.
Q3. How would the mounting height influence your decision regarding sign board size?
The bigger your board will have to be, the higher you mount your sign. For example, a sign mounted 15 feet above ground level will appear smaller from the ground and therefore will require an increase in size by 20%.
Q4. How big should your temporary directional signs be?
You need an 18″x24″ board made out of corrugated plastic, which should be mounted using metal H-stakes. This size will be big enough for drivers to see it even from far away.
Q5. How do you size your custom signs to get the maximum benefit from your raw factory sheets?
Factories produce raw PP corrugated sheets that are always 48″ × 96″ in size. In order to avoid paying your factory for any scraps that will not be useful to you, you should size your custom signs to be divided evenly from these dimensions (for example, eight 18″ × 24″ signs per sheet).
Q6. Is 18×24 a good size for a welcome sign?
Yes, 18″ × 24″ is a perfect measurement for your welcome sign. It will fit nicely on a regular easel and your guests will be able to read it easily from 15 to 20 feet away.

Depending on whether you need signs for an office, retail store, event, street name, or billboard advertising, each situation will require a specific dimension.
