Publishing on Kindle: Guidelines for Publishers

3.7.3 Table Guideline #3: Create Simple HTML Tables

Use the <table> tags to create simple tables that have standard rows and columns. These tables

display as tables on currently available Kindle devices and Kindle for iPhone. On Kindle 1, these tables

are flattened (all of the content appears in one column). KF8 has support for nested tables and merged

cells, but Amazon recommends that publishers use this judiciously and only when necessary.

Colspan and rowspan attributes should be less than or equal to the total number of columns or rows (as

appropriate) in the table.

3.7.4 Table Guideline #4: Split Tables as Needed

There are times when it may be necessary to format a table as an image, but the image is still too large to

be legible on one Kindle screen. In this case, it is a good idea to split the image. The following example is

a guideline to use when splitting a 2-page table. This logic can be extended for multiple-page table

images.

Example: Split the image in half horizontally 60% of the way down the image, then split the header, copy

it to the bottom half of the image, and stitch these into a new image. The final two images should then be

the same size, with table headers.

Revise the source image, not the converted GIF; otherwise, the image will be converted into GIF format

twice, which might result in lower quality.

3.7.5 Table Guideline #5: Optimize for Maximum Table Size

Optimize tables to be no larger than 10 Kindle screens. A Kindle screen is approximately 24 rows of 60

characters, although the Kindle DX shows more characters. The character limit is the maximum number

of characters in any one row. There are a limited number of combinations for a table that looks like this

(see below). If a table has more characters than the maximum number specified below (given the number

of rows), split the table into smaller tables or images, as described in section 3.7.4, Table Guideline #4:

Split Tables as Needed. In this case, characters are non-formatting characters (the actual text that a user

sees when looking at the contents of a table).

Adobe Digital Editions Compatibility Guidelines 3.8

3.8.1 Adobe Digital Editions Compatibility Guideline #1: Use Unique Item IDs

When using Adobe Digital Editions, make sure that the item IDs in the manifest are unique. Adobe Digital

Editions does not enforce uniqueness of IDs, which is incorrect according to the IDPF standard.
