# Banner best practices

## Overview

Follow these guidelines to design banners that display well on every device and get clicks. To start faster, use the Opensense [Canva templates](#canva-templates).

## Size and resolution

<dl class="kb-insights-summary">
  <div><dt>Size</dt><dd>580 × 150 px displays well on all devices. Match the width of your signature.</dd></div>
  <div><dt>Resolution</dt><dd>72 dpi.</dd></div>
  <div><dt>Image dimensions</dt><dd>Make the image 1× or 2× the dimensions set in the HTML, so it does not scale up beyond its original size.</dd></div>
</dl>

## Calls to action

Use a clear call to action (CTA). Specific CTAs, such as "Get your gift" or "Leave a review", do better than "Click here".

## Animation

Banners can be animated GIFs. Movement catches the eye and tends to get more engagement.

## Exporting from design tools

<dl class="kb-insights-summary">
  <div><dt>Photoshop and Illustrator</dt><dd>Export the banner at the recommended size and resolution.</dd></div>
  <div><dt>Canva</dt><dd>Canva can lower the image quality on export. Export the banner at a much larger size, then resize it to your banner width in a tool such as Photoshop.</dd></div>
</dl>

## Canva templates

Opensense made Canva templates for common banners. Choose a template, add your brand's message and visuals, and download the banner image.
