Choosing the Perfect Squarespace Header Image Size

Images are an integral component of any website, providing context and helping to tell your brand’s story. But these must also be formatted correctly based on size and orientation.

Narrow width images may look pixelated on desktop monitors and large files can slow page load speeds significantly. Squarespace best practices recommend keeping images 1500 pixels wide.


Squarespace makes creating images for your website less daunting by providing clear guidelines regarding image sizes for different types of imagery. For instance, banner images (those featured at the top of most Squarespace websites) should ideally range between 1500-2500 pixels wide to ensure they display beautifully when shown full size on computers, tablets and phones screens.

Product images should ideally range between 1500-2500 pixels to avoid them becoming pixelated when stretched or cropped to fit in Image Blocks that appear on product pages of your site. While Squarespace allows uploads up to 20MB, for optimal site speed and performance they recommend keeping image file sizes to about 500KB or lower.

Color mode should also be carefully considered when uploading images to Squarespace, as Squarespace recommends RGB files over CMYK ones as the latter do not always display correctly when viewed on mobile devices.

Your header image size can also be configured by going into Settings > General and selecting one from the Image Size drop-down menu. Be sure to choose something consistent with your brand and style guidelines – such as using an option from this drop-down.

As well as their file sizes, you’ll want to ensure that your images are formatted appropriately before uploading them to Squarespace. Use either Mac’s built-in Image Editor or photo-editing software tools like Lightroom to prepare your images before uploading them – this will help make sure they look their best while not adding extra pixels that could slow down your website.

Finally, make sure your images include descriptive alt text for optimal SEO purposes and visitor accessibility. Enter it directly in the caption field of an image, or use an Image Block with custom alternative text that appears when hovering over an image on a desktop or laptop screen.


Banner images (also known as hero images) are large photos that appear at the top of most Squarespace websites, often stretching side-to-side with no margins and serving as visitors’ first glimpse of your site. As this banner image will likely be the first thing people see when visiting, it must be of high-quality; blurry or pixelated pictures will turn potential customers away!

Squarespace does an outstanding job at automatically resizing images to fit different screen sizes and resolutions. Once an image is uploaded, Squarespace generates six copies in different sizes and resolutions so your website remains legible across devices.

If you want to put in some extra work, image editing tools can be used to reduce both size and quality before uploading them to Squarespace. Be mindful that file sizes don’t exceed 500KB as large files may slow down your website.

Another thing to keep in mind when uploading images to Squarespace is their aspect ratio, or width/height relationship. By default, Squarespace uses an aspect ratio of 1:1 but for optimal results use one that matches up with your image’s aspect ratio in order to prevent stretching or cropping of your photo.

Keep this in mind when using Squarespace: always utilize high-quality images. Not only will this enhance the appearance of your site, but it will also aid SEO and user experience. In addition, include alt text for each image to let search engines know what the picture represents.


Squarespace header images are large, full-width images that appear at the top menu bar (or “nav”) bar of your website. This often features your logo, some form of text to inform visitors what it’s all about and an action button encouraging readers to contact or purchase products or services offered by your business.

Ideal dimensions for Squarespace header image sizes should be 2000 x 2500 pixels to ensure it can fit on all devices without becoming pixelated or blurry.

Before your Squarespace header images go live, it is crucial that they are compressed. This will reduce loading times and improve SEO rankings and visitor experiences alike.

An effective way to compress an image is using a free online photo compressor like PNGOUT. This tool will transform JPG files into PNG formats that are smaller while maintaining quality and resolution; additionally it supports thumbnail creation allowing for consistent aesthetic across your website.

One method of reducing image file sizes is by editing software such as Photoshop or Lightroom to remove any extra details from it, such as shadows or extra edges around it. With these programs you can also crop the image for upload back onto Squarespace sites.

Avoid enlarging images as this will only result in them appearing grainy and blurred on all devices – from desktop computers to mobile phones. Instead, strive to start with images at least 1500 pixels wide – this will ensure they look crisp and clear across the board.

As you upload images to your Squarespace site, it’s also essential that the file names be descriptive of what they depict. This will enable Google to understand what the image represents and ensure it will show up in search results. To achieve this result, include keywords in your file names; exclude characters like % or? and use only letters, numbers or hyphens when writing filenames.


When formatting images for the web, several things must be kept in mind when formatting images. You need to pay close attention to both dimensions and file sizes of your images – this will impact their loading speed on your website as well as quality. In general, you should aim for images under 500KB to keep loading times speedy while maintaining quality images.

Another thing to bear in mind when designing an image is its size and aspect ratio. Square images will help prevent stretching or distortion while RGB color mode ensures your images display correctly across devices.

Furthermore, images with borders or text should be avoided since these cannot be easily styled by Squarespace’s designer and may prove distracting for your visitors. Incorporating text directly into an image file should also be avoided to keep a professional appearance.

Finally, it is essential to use images with proper titles and alt texts, both of which can improve SEO rankings on Google image search. Make sure that keywords are included in the image name while choosing an engaging title relevant to your page – use png images if any contain text as they don’t become blurry when compressed like jpg ones do.

Banner images on websites are the first thing visitors see, so it’s crucial that it stands out. To do this, make the banner image between 1500-2500 pixels wide – this ensures it won’t crop on mobile devices and makes it easy for visitors to click.
