Welcome! This post contains 7 best selling medium content books on Amazon with sub-niche ideas to help you get started.
I have made most of my royalties from Amazon KDP by publishing medium-content books.
Luckily, I created my first batch of kdp books as writing prompts journals that fall under the umbrella of medium content books!
I also published low-content books like journals, sketchbooks, and composition notebooks but medium-content books sell well over time and I can price them a bit higher.
Most importantly, medium-content books are comparatively harder to create therefore the competition is lower as not all publishers are willing to put that much time and effort.
And today in this blog post, I will be sharing some of the best-selling medium content books on Amazon. By best-selling medium content books, I am referring to those books that are currently generating good sales.
You can take this info as a starting point for your niche research or you can publish similar books just better than already created ones.
So, without further ado let’s just read more about these best-selling kdp medium content books.

They are primarily intended for readers who have difficulty reading standard-sized text due to visual impairments, such as those with low vision, seniors, or individuals with certain medical conditions that affect their eyesight.
As per kdp, large print books should have a font size of 16 and above. So, you can easily create large print books by increasing the font size and targeting a huge kdp niche. These books are very popular among seniors and people with low vision.
As you can see in the screenshot above, this large print word search puzzle book is targetting people with low vision. All the publisher did to create this book is increased the font size.
You can do a similar thing with your normal books and target a totally different niche.
Next, I did a quick search on Amazon for “low vision activity book” and found this keyword has just over 570 Amazon search results which means the competition is still very low.
