Choosing the right billboard ad size is one of the most strategic decisions you’ll make for any outdoor campaign. The size you pick affects visibility, readability, creative possibilities, cost, and—most importantly—how quickly a passerby understands and acts on your message.
When navigating the Canadian Out-of-Home (OOH) advertising landscape, understanding dimensions is the first step toward a high-impact campaign. While Canada shares some similarities with the American market, the Canadian industry has its own unique «Golden Standards» designed to capture attention in major hubs like Toronto, Montreal, Edmonton and Vancouver.
In Canada, billboard sizes are categorized into three primary dimensions that offer maximum reach and visibility:
Superboards (Bulletins): 14 feet high by 48 feet wide
The «King of the Highway.» These are the massive displays found along major arteries like the 401 or the QEW. They offer the largest canvas for brands looking to establish dominance and prestige.
Posters (Horizontal): 10 feet high by 20 feet wide
This is the most ubiquitous billboard size in Canada. Positioned primarily on surface streets and in urban high-traffic areas, the 10’x20′ format is the workhorse of Canadian advertising, providing high frequency and localized impact.
Transit Shelter Ads (TSA): 5.7 feet high by 3.9 feet wide (approx. 68" x 47")
In Canada’s densest cities, street-level visibility is key. While technically «street furniture,» these are often referred to as «mini-billboards.» They are strategically placed at eye level to capture both pedestrian traffic and commuters in transit.

How to Choose the Best Billboard Ad Size Based on Your Campaign Goals
Not all campaigns need the largest Billboard Ad Size. Sometimes, a medium or small Billboard Ad Size delivers stronger engagement.
Here’s how to match your goals with the perfect Billboard Ad Size:
Goal: Brand Awareness
You need broad visibility → choose the largest available Billboard Ad Size.
This ensures instant recognition, even from a distance.
Goal: Promote an Offer or Event
A medium Billboard Ad Size offers enough space for clear messaging while staying close to high-density audiences.
Goal: Target Local Neighborhoods
Goal: Drive Conversions
billboard banner ad size — Why Bigger Isn’t Always Better
A common misconception is that the largest Billboard Ad Size always wins.
But that’s not true. Sometimes the most effective Billboard Ad Size is the one that matches:
- The traffic speed
- The audience type
- The surrounding environment
- The distance between viewer and board
- The campaign’s messaging style
For example, promoting an urgent call-to-action near a point-of-sale location works best with a medium Billboard Ad Size, not a massive highway board.
How Billboard Ad Size Influences Design Strategy
Your creative team must adapt design depending on the Billboard Ad Size.
Here’s how size affects visuals:
Small Billboard Ad Size
- Concise messaging
- Simple layouts
- Bold fonts
- Close-range readability
Medium Billboard Ad Size
- Balanced graphics
- Short headline
- Clear branding
- Key detail allowed
Large Billboard Ad Size
- Balanced graphics
- Short headline
- Clear branding
- Key detail allowed
A great creative concept fails instantly if mismatched with the wrong Billboard Ad Size.

Naturally, Billboard Ad Size affects cost — but not always the way you think.
1. Larger Billboard Ad Sizes cost more upfront, but because they reach massive audiences, they often deliver the lowest cost per impression.
2. Smaller Billboard Ad Sizes cost less and can be hyper-targeted, giving you incredible value in dense urban areas.
