How to design a roadside sign is a big subject, which includes select sizes of the signs.

Sign Sizes

The size and amount of lettering is very important in sign design. The size of the sign shall be dependent upon the size of lettering required and the length of the message. The length of the message should be kept as short as possible. Signs should be sized to adequately fit the message in accordance with the sign layout guidelines provided above. Signs and Messages should be larger if:

• There are factors that impact the driver, such as a complex driving environment in an urban situation.
• In areas with a high collision rate, where the collisions can be attributed to drivers missing the sign.
• If there is a known challenged‐driver population in the area.

Under certain circumstances, in city centres for example, the locations for installing signs of a certain size may be limited by boulevard space and structural limitations of the sign support structure. In these cases, it may be necessary to either redesign the sign or divide sign information over two or more signs.

Other locations on highways may also have sign size restrictions such as overhead structures over travel lanes, and on exit ramps. In areas with restricted clearances the height of sign may also be restricted.

Placement Considerations

Proper positioning of signs is an important element in the overall control of traffic within a roadway network.

When carefully planned and applied, it significantly improves the driver’s ability to navigate through the network. Conversely, when neglected it may contribute to operational and safety problems. Consequently, it is important to standardize the position of signs so the drivers can quickly locate them and spend more time reading thesigns rather than looking for them.

Due to the changing roadway environment, the standardization of sign position is not always attainable. As a general rule, signs should be placed in the most advantageous position and adapted to the road design and alignment. The following guidelines should be use when locating traffic signs and devices along a roadway.
