Publishing on Kindle: Guidelines for Publishers
5.3 Optimizing Content for the Graphic Novel Experience
5.3.1 Optimizing Tap Targets
Tap targets should effectively cover 100% of the screen. This ensures that the user gets a magnified
experience whenever the user double taps the graphic novel.
5.3.2 Optimizing View Panels
View panels should be 150% of the tap target by default. It is acceptable to use different size view panels
to emphasize a specific action scene within the tap target.
Position view panels so that they convey where the primary action scene occurred on the original page.
Typically, view panels are horizontally aligned to the left, center or right edges and vertically aligned to the
top, center or bottom edges.
When preserving context across multiple panels, it is acceptable to overlap slightly with other view
panels.
5.3.3 Optimizing for Wide or Tall Action Scenes
To use the default 150% default zoom factor, an action scene often needs to be divided into two view
panels (typically a left and right or top and bottom). This is a better user experience than using a smaller
zoom factor, because it preserves accessibility and gives the user a higher resolution reading experience.
Split the tap targets so that the first tap target is between 50 and 75% the width of the entire area, and the
second tap target is the remaining amount necessary to reach 100%. This ensures when a user double
taps an area near the middle of the action panel, they experience the first view panel first, and then the
second view panel when they move forward.
To preserve the flow of the action, view panels should display a small amount of overlapped action.
