Size and PDF Comparison: Sony DPT-RP1, Kobo Aura One, Kindle (Video)

Some people were wondering how the Kobo Aura One with KOReader compares with the Sony DPT-RP1 when it comes to reading PDFs.

KOReader helps enhance the Aura One by adding more features for PDFs than the stock software offers, but it can’t do much to make up for the smaller screen size.

The 7.8-inch screen on the Kobo Aura One is a nice step up from typical 6-inch E Ink screens, but it still can’t compare to the 13.3-inch screen on the Sony, which was designed specifically for PDFs.

It’s so much larger that it’s almost like comparing two completely different types of devices, even though both support PDF and both have E Ink screens.

I put together a quick video to help show the massive size difference between the Sony DPT-RP1 and Kobo Aura One, along with a typical 6-inch ereader using the Kindle Paperwhite as an example.

All show the same PDF to get an idea of how it scales on the different size screens.

The Kobo Aura One works pretty well in landscape mode if you don’t mind viewing about half a page at once. It doesn’t offer any notes features however, just highlights. But if you can get by with those limitations it’s a pretty good PDF reader, especially if you don’t want to spend a small fortune on the Sony. However, if you want be able to easily read a full page at once and be able to add notes directly on the screen or in a separate notepad, the Sony DPT-RP1 has a big advantage there.
