How to Choose the Right Postcard Ad Size
Match your ad space to the amount of information a customer needs to make a decision.
Start with the message
A small space works well for a familiar brand, a single seasonal offer, or a concise service message. A larger space gives you room for photos, multiple services, testimonials, or a detailed offer.
Avoid choosing a size based only on price. Choose the smallest size that lets your main message remain easy to read at arm’s length.
Keep the visual hierarchy simple
Your business name, offer, and response method should lead the eye. If any of those elements feel crowded, the ad likely needs fewer words or more space.
Before printing, view the design on a phone at roughly postcard size. If the headline and phone number are hard to spot, simplify it.
Plan for repeat use
A larger ad can be useful when you want a design that will work across several monthly mailings. Build a flexible layout so the offer can change without rebuilding the entire ad.
Build from a simple creative brief
Give the designer a short brief: who the ad is for, the single result you want, the offer, the proof point, and the required contact method. A concise brief protects the design from becoming a list of every service you offer.
Have someone unfamiliar with the business look at the proof. If they cannot say what you do, what the offer is, and how to respond, revise the hierarchy before approving it.
Avoid a crowded final proof
The most common creative mistake is trying to make every sentence equally important. Remove secondary details before shrinking the type or adding another visual element.
Always inspect the final proof at a realistic printed scale. What feels roomy on a large screen can feel very different in a person’s hand.
