Analyze the scale of the object being measured

The object to be measured is the size of printed letters on a page. Printed letters are extremely small, typically measuring only a few millimeters in height or width.

Evaluate the given unit options

• feet: Too large. A letter would be a tiny fraction of a foot (e.g., \(0.01\text{ ft}\)), which is hard to read.
• kilometers: Extremely large. Used for geographic distances, completely impractical for page layouts.
• inches: Still too large. A standard letter is usually less than \(0.1\text{ inches}\) tall, leading to awkward decimal values.
• millimeters: Highly appropriate. A typical printed letter is about \(2\text{ to }4\text{ mm}\) tall, which gives clean, easy-to-read whole numbers.
