# Data Size of Manuals

## Finding a Manual's Data Size

To find the data size of a finished Nintendo DSiWare e-manual, check the BLZ file created by a binary export of the project.

## Making a Rough Estimate of a Manual's Data Size

You can make a rough estimate of a Nintendo DSiWare e-manual's size from the volume of text and the images used.

Note: This is only a rule of thumb. The actual data size may deviate considerably depending on page content and source images.

### Text Data Size

One thousand characters of text uses roughly 0.4 KB of space.

### Image Data Size

Once compressed, the size of the image data will be approximately 90 percent of the total size of the GIF images used in the Nintendo DSiWare e-manual.

Note: The numbers in this table are given as guidelines. Image data with long horizontal stretches of the same color are smaller in size.
