Spacing: Proper spacing between text lines and graphic elements avoids overcrowding.
Layout Design: Organized layouts aid in better information dissemination.

Let's take a closer look at the mathematics behind legibility. The Luminance Contrast Ratio, a critical factor, is calculated as follows:

Luminance Contrast Ratio: \[L = \frac{(L1 + 0.05)}{(L2 + 0.05)}\]

where \(L1\) is the relative luminance of the lighter of the colors and \(L2\) is the relative luminance of the darker of the colors. This formula helps in determining the appropriate contrast level for text to ensure it's readable.

Another mathematical concept involved in spaced layout is the Golden Ratio. The ratio is expressed as:

Golden Ratio: \[\phi = \frac{1 + \sqrt{5}}{2} \approx 1.618\]

Using the Golden Ratio in layout design can create visually appealing and easily navigable documents, thus enhancing legibility.
