Whether you call them banners, headers, heroes or carousels one thing is certain – they are an essential component of eCommerce success. The chances are that they will be one of the first things your customers see when they land on your homepage, so it’s important to get them right. Done correctly, they can drive sales and conversions. On the other hand, if they are created carelessly they are likely to have the opposite effect and instead confuse customers.


In this blog post we’ll be laying out the banner basics. This is helpful to know regardless of whether you’re creating the banner yourself or hiring a designer. After all, the clearer and more specific your brief is; the less room for interpretation there is.


When it comes to choosing your banner size, the choice you make should depend on the purpose of the banner within your homepage. If you have one central message that you really want to drive home, a full page background image will work best. If you want to show off multiple products or want to direct visitors to different areas of your website, a smaller banner will be more useful. Here’s some examples:


Slack have opted for a full page animated background image. The navigation is tucked away which means your immediate focus is on the visuals. This suits their business because they are selling one product, so only have one central message. The animation and simple design gives their homepage a modern feel, which is consistent with Slack’s branding.

Pretty Little Thing

Pretty Little Thing, whereas, have chosen a slightly smaller banner. The primary purpose is to draw attention to their current collaborative collection with Maya Jama which is a key selling point. But it also leaves room to promote their valentines collection and boast about their delivery deals, which is often a deciding factor when deciding to complete a purchase.

Banner sizes are measured in pixels and , if you can’t already tell from the examples above, work better in landscape rather than portrait. The 6 most popular banner sizes are: 1920 x 1080, 1280 x 375, 1170 x 569, 1024 x 300, 800 x 200 and 570 x 274. We recommend that 1920 x 1080 is the biggest that you go, beyond this and the size will begin to affect your websites speed. Your banners can be any size you wish, however, as a general rule of thumb we recommend that they are wide and short rather than thin and long.  


A good banner isn’t possible without good photography. Photos are one of the key factors in determining whether visitors continue scrolling through your site or leave and take their custom to a competitor.  If you’re going to be shooting your own banner photos, remember to follow a 4:1 ratio. As we’ve already mentioned, banners work best in landscape so shoot your photos in landscape mode to maximise your photos usability. It’s really difficult to crop a portrait photo to landscape whilst still retaining your subjects full visibility. What’s more, try and stick to the rule of thirds. This dictates that visually compelling photos are created by dividing pictures into thirds and placing the subject matter at the cross over points. Following this also makes sure that your choice of photo will leave room for text.

However, if your business is just starting out the chances are you don’t have the budget to pay for professional photos of your products or professional photography equipment to do it yourself. Whilst smartphone cameras will suffice, not all of us have a knack for photography. If you’ve found yourself in this situation don’t worry! There are plenty of free stock image websites that you can get banner photos from, here are some of our favourites:

Colour Scheme

During the creative process it’s good to stick to your branding – but it’s equally important to understand the basics of colour psychology and how they can maximise the impact of your banners.

Here’s a basic rundown of what each colour represents and how it may affect your eCommerce store:

  • Yellow – optimism, energy, treasure, hope, life, cheerfulness, happiness
  • Orange – creative, friendly, enthusiastic, joy, warmth,
  • Red – passion, speed, love, fire, excitement, urgency, violence, aggression, strength
  • Purple – royalty, luxury, wisdom, dignity, status,
  • Pink – impactful, caring, romance, femininity, calm
  • Brown – relaxation, luxury, nature
  • Green – growth, rebirth, nature, prosperity, abundance,
  • Blue – strength, tranquility, assurance, trust, responsibility, intelligence
  • Black – bold, powerful, confident, sophisticated, emotion
  • White – balance, pure, innocence, cleanliness, efficiency


When it comes to the text that will add the informative aspect to your banner, we recommend 3 key ingredients. Firstly, the banner should include your logo. This is important for brand awareness purposes. Out of the three ingredients, however, the logo should be the smallest. The second aspect is a compelling call-to-action (CTA). A banner should have a purpose that is consistent with the goal of your business. Where do you want your customers to go? Within the world of eCommerce the most common banner CTA is usually a ‘shop now’ button. Finally your banner should your businesses value proposition – what does your company do? What makes them unique? Convince your customers to choose you over your competitors. One way of doing this is by boasting about recent customer reviews. Research shows that reviews are a huge factor in driving conversions since approximately 61% of customers refer to reviews before purchasing a product.

Whilst it’s important that your banner incorporates all three aspects, having a easily readable banner is also important. For this reason we recommend having a maximum of 4 lines of text, if you go higher than this your website visitors are quite simply not going to read any of it. Another key consideration is accessibility for all users. For this you may wish to think about your text size and colour. If you want to take your banners to the next level you could also incorporate some personalisation by showing users tailored products based on their past on-site behaviour. Currently only 30% of businesses utilise personalisation on their website, so being one of the first to adopt this could be really beneficial.

Carousel/Animated Banners

If you’ve done your rounds on the internet you’ll have probably come across a website that has a rotating/carousel website banner. With the ability to communicate several messages to your customer, it’s easy to understand why you may wish to implement a rotating banner on your website. However, in practice they are often a wasted effort. Research shows that rotating hero banners aren’t actually that effective. A study by Notre Dame University shows that the first image receives 84% of all clicks, so images after that will rarely get noticed. What’s more they can diminish your customer experience by increasing your website load time, and as we know customers are becoming more and more impatient!

Despite this if you still want a rotating banner, our top tip is to include no more than 6 images. Evidence shows that if we are shown more than 6 products our brains automatically switch off because the choice is too demotivating.

With this in mind you’re not armed with all the tools you need to set about creating your own website banners. We hope you found this guide helpful, if you’re thinking about giving your business a boost by investing in a new website get in touch!
