Notes

Different screen sizes will result in a variety of image sizes.

If your image ratios are not exactly the same as what we’ve recommended, we will crop the images into these ratios for you.

JPG and PNG image types works best.

The width of the banner shrinks or widens depending on the width of your screen, the height stays the same. We recommend uploading 3840 x 512px.
​

Desktop: The width of the banner shrinks or widens depending on the width of your screen, the height stays the same. We recommend uploading 2500 x 600px.

Mobile: The image will be cropped to a ratio of 4:1 (width:height). You can edit and select the area shown in mobile by selecting Mobile View (as shown in the bottom left above).

Desktop: we recommend uploading 640 x 372px, the ratio is 1:0.58.

Mobile: the image will be cropped to a ratio of 3.15:1.

Desktop: we recommend uploading 440 x 248px, the ratio is 1:0.56.

Mobile: there are no lesson images.

Desktop: we recommend uploading 220 x 220px, the ratio is 1:1.

Mobile: the ratio stays the same.

Desktop: we recommend uploading 620 x 864px, the ratio is 0.7:1.

Mobile: the ratio stays the same.

Desktop: we recommend uploading 300 x 300px, a 1:1 ratio so your logo stands out more. Other ratios will also work.

Mobile: the ratio stays the same.

There is no single preferred choice for PDF sizes as there are a variety of screen sizes.

Both portrait and landscape PDFs work on our platform, however users naturally hold their phones in ‘portrait view’ so portrait PDFs will require less zooming than landscape PDFs on mobile.
