5 Surprising Comparisons: Understanding 20cm Lengths

Have you ever found yourself pondering over the significance of measurements in everyday life? Whether it's measuring the length of your work desk, the height of a toy, or even the depth of your kitchen sink, understanding how different lengths compare can make a world of difference. Today, let's dive deep into one such length, 20cm (approximately 7.87 inches), and explore five surprising comparisons that will not only educate but also fascinate you.

Comparison 1: The Human Hand

When we talk about 20cm, an immediate comparison comes to mind - the human hand. Depending on the size, the average adult hand's length from the wrist to the tip of the middle finger can be quite close to 20cm.

• Small Hand: For individuals with smaller hands, 20cm might cover from the wrist to just beyond the middle knuckle.
• Medium to Large Hand: For those with medium to large hands, this length could span from the wrist to just below the fingertips.

This comparison is particularly useful when you need a rough estimate of a 20cm length without a ruler handy.

Practical Uses

• Measuring Objects: You can easily measure small to medium-sized objects like books or gadgets by using your hand.
• Adjusting Settings: When setting up a screen or monitor at the right height for ergonomic viewing, this measurement can come in handy.

The evolution of smartphones has brought them closer to the 20cm mark in length, making this comparison quite fascinating.

• Flagship Models: Many premium smartphones, like Samsung Galaxy S21 or the iPhone 12, come close to or exceed 20cm in length.
• Mid-range Models: Some mid-range phones from companies like Xiaomi or OnePlus also hover around this length.

Comparison 3: Common Stationery Items

A ruler, pencil, or pen can all be proxies for the 20cm length.

• Ruler: Most standard rulers are 30cm, but if you halve that, you get 15cm. However, many drafting rulers come in 20cm lengths.
• Pencil or Pen: The average length of a freshly sharpened pencil or pen cap is around 18-20cm, giving you a good ballpark.

Stationery Usage

• Sketching: Using a 20cm scale for sketching can give you a small, manageable space for drawing or annotating documents.

Stationery Lengths in Perspective

Stationery items are not just tools but also makeshift rulers:

• Desk Organization: Arranging your desk space, keeping 20cm between your most-used items can create a clutter-free workspace.
• Educational Tools: For students, using stationery to measure items without a tape measure can be quite handy.
