Choosing the Right Size for Google banner Ad

Now that we’ve covered the basics, let’s talk about how to choose the right Google banner ad size for your specific campaign. Here are a few tips to help you decide:

1. Know Your Goals: What are you hoping to achieve with your ads campaign? If you’re looking to drive clicks, a medium rectangle (300×250) might be your best Google Ads design. If brand awareness is your goal, a leaderboard (728×90) could be more effective due to its prominent placement.

2. Consider Your Audience: Think about where your audience spends their time. If they’re primarily on mobile, opt for a mobile leaderboard (320×50). If they’re desktop users, a wide skyscraper (160×600) might be more effective.

3. Placement Matters: The placement of your Google banner ad on a webpage can significantly impact its performance. Leaderboards and medium rectangles often perform well because they are highly visible. Experiment with different placements to see what works best for your audience.

4. Design for Engagement: Larger ads like the half-page (300×600) provide more space for creativity. Use this space wisely to create an engaging, visually appealing Google Ads design that draws users in.

Formats Supported by Google Ads

There are mainly 3 types of formats you can upload on Google banner ads: JPG, PNG, and GIF. It depends on which ad you think would be more appropriate to increase your reach and viewable impressions. 

How to Make Ads?

So, you’ve scrolled through the mountain of Google ad sizes, figured out which ones work best, and now you’re itching to start with Google Ads design, right? You’re in the right place. Let’s break it down step by step and turn your ideas into a Google banner ad that catches eyes and wins clicks.

Learning how to make ads can sound technical, but it’s not. Once you know what size to go for, it’s all about getting creative, and keeping a few golden rules in mind.

Step 1: Know Your Ad Sizes Like the Back of Your Hand

Before you jump into designing a Google banner ad, you need to know which size you’re working with. Google offers a ton of options, but some ad sizes perform better than others. The most popular ones to keep in your back pocket are:

• 300 x 250 – Medium Rectangle
  
• 728 x 90 – Leaderboard
  
• 160 x 600 – Wide Skyscraper
  
• 320 x 50 – Mobile Banner
  

These are the usual suspects that work well across websites and devices. If you’re making responsive display ads, you won’t need to pick a single size, Google does the adjusting for you. But if you want pixel-perfect control, stick with the standard sizes.

Step 2: Use the Right Tools for Google Ads design

Now comes the fun part where you start with the Google Ads design. And no, you don’t need to be a Photoshop pro. There are some easy-to-use tools out there that make ad design feel like a walk in the park.

1. Canva

If you love drag-and-drop simplicity, Canva is your go-to. It’s loaded with templates, and you can even type in your custom pixel size before starting. Whether you’re designing a 300 x 250 or a 970 x 250 billboard-style Google banner ad, Canva’s got your back.

2. Bannersnack (Now called Creatopy)

This one’s tailor-made for banners and display ads. It lets you create multiple sizes at once. It’s super handy if you’re doing a full campaign rollout. Plus, it’s packed with animated features to make your Google banner ads pop.

3. Vista Create

Think of Vista Create as Canva’s cousin. It’s clean, quick, and packed with design goodies. You just plug in the size you want and start creating. Whether you’re working on a static Google banner ad or something a little fancier, Vista Create makes it a breeze.

Step 3: Keep These Design Tips Up Your Sleeve

Now that you’re in the driver’s seat, here are a few must-know tips to steer your ad design in the right direction:

Be Consistent with Your Branding

Ever seen an ad and instantly knew which brand it was (without even reading the text)? That’s the power of consistent branding. Use the same fonts, colors, and logos across all your Google Ads design so your brand sticks in people’s minds.

Don’t Skip the CTA (Call-to-Action)

What’s the point of an ad if no one clicks it? A strong, clear CTA like “Shop Now,” “Learn More,” or “Get the Deal” gives your audience direction. Without it, your ad is like a map without a destination.

A/B Testing is Your Secret Weapon

One design might get 10 clicks, and another might get 200. All because of a small tweak. Use Google Ads A/B testing to see what works. Try changing colors, headlines, or even just the button text of your Google banner ad. Keep testing, keep learning. 

Stay Simple, Stay Smart

When it comes to Google ads, less is more. Instead of throwing everything but the kitchen sink into your design, stick with one strong image, a short message, and a clear CTA. Clutter confuses. Simplicity sells.

Step 4: Upload to Google Ads and Set Your Campaign Live

Once your ad designs are ready, head over to your Google Ads account, go to the Display Campaign section, and start uploading your creatives. Make sure to test them across devices and preview how they’ll appear. Choose your targeting, set your budget, and hit go!

And there you have it—you just made your first Google banner ad!

Frequently Asked Questions

1. What is the best size for Google banner ad?

Ans. The best-performing Google display ad sizes are usually 300×250 (Medium Rectangle), 728×90 (Leaderboard), and 160×600 (Wide Skyscraper). These formats are widely supported across websites and mobile apps, giving your ad more visibility. While Google supports many ad sizes, sticking to these common ones increases your chances of getting better impressions and clicks.

2. Do I need to be a designer to make Google display ads?

Ans. Not at all! Today, you can use beginner-friendly tools like Canva, Vista Create, or Bannersnack to create professional-looking ads. These tools offer ready-made templates and let you customize designs by choosing your own fonts, images, and brand colors—no design degree required! Just bring your creativity and you’re good to go.

3. Why is a call-to-action (CTA) important in a display ad?

Ans. A call-to-action (CTA) tells your audience what to do next—like “Buy Now” or “Learn More.” Without a CTA, people might look at your ad but won’t take any action. A clear CTA boosts engagement and helps convert viewers into actual customers. It’s one small element that can make a big difference.

4. How can I test if my ad design is working well?

Ans. You can use A/B testing within Google Ads to compare two different versions of your Google banner ad. This helps you see which one gets more clicks or conversions. Sometimes a small change—like a different headline or background color—can drastically improve results. Testing helps you spend your ad budget wisely and get better ROI.

5. What’s the biggest mistake to avoid when in Google Ads design?

Ans. One common mistake is overcrowding the Google banner ad with too much text, too many images, or unclear messaging. If the ad feels messy, people won’t know what to focus on—and will scroll right past it. Keeping your ad simple, clean, and focused helps grab attention and communicate your message clearly and quickly.
