When working on tasks that require precision, such as sewing, carpentry, or even baking, knowing how to measure fractions of an inch accurately can be a game-changer. Whether you're adjusting a pattern for a perfect fit, cutting a piece of wood to size, or ensuring your pastries are uniform, understanding how to measure distances like 2/3 to 6/7 can be incredibly useful. Here are 7 simple tricks to help you measure these fractions with ease and precision.
1. Using a Ruler or Tape Measure with Fractional Marks
Most standard rulers and tape measures come with markings for common fractions of an inch, including:
- 1/16
- 1/8
- 1/4
- 1/2
However, for measurements like 2/3 or 6/7, you might need to do a bit of estimation or calculation:
- 2/3 of an inch can be found by finding the 1/3 mark, which is usually between the 1/2 and 1/4 marks, and then doubling that distance.
- 6/7 would require a bit more division. It's nearly 0.857 inches, so you would measure 8/16 (1/2 inch) plus an additional 5/6 of the space between 8/16 and 9/16.
Here's how you might visualize this:
|<- 1/4 ->|<- 1/4 ->|<- 1/8 ->|<- 1/16 ->|<- 1/32 ->|
| 2/3 | | 6/7 |

2. Use the Nearest Whole Numbers
A quick and dirty method is to round to the nearest whole number, subtract the nearest fraction below, and then measure:
-
For 2/3, you would:
- Recognize that 2/3 is close to 1/2.
- Take 1/2 inch and add one-third of the space between 1/2 and 1 inch.
-
For 6/7, you would:
- Recognize that 6/7 is close to 1 inch.
- Subtract 1/7 of an inch from that (which is about 0.14 inches).
3. Fraction Conversion to Decimal
Knowing the decimal equivalent of fractions can simplify your measurements:
- 2/3 = 0.666... or about 10/16 inches on a ruler.
- 6/7 ≈ 0.857 inches or approximately 14/16 inches with some extra.
This conversion can be handy when working with digital tools or when the markings on your ruler don't quite match what you need.

4. Trisection and Heptisection Techniques
If your ruler doesn't have the fractions you need, you can:
- Trisect a distance (divide into three equal parts) to get 1/3, and then add 1/3 again for 2/3.
- Heptisect (divide into seven parts) to find 1/7 and then add 5/7 for 6/7.
Here’s how you could trisection a 1-inch strip:
|___1/3___|___1/3___|___1/3___|
<p class="pro-note">✨ Pro Tip: Mark your divisions lightly with a pencil so you can erase and start over if needed.</p>
5. Double Checking With a Calculator or Measuring Tool
For absolute accuracy, especially in professional work, using a calculator or a digital measuring tool:
- Enter the fraction into a calculator that can handle fractional arithmetic.
- Some measuring tools and digital calipers have features to measure and display fractions.
6. Use Reference Points and Spacing
If you're measuring along a flat surface:
- Create reference points for common measurements. For example, mark 1/4 and 1/2 inch, then calculate the midpoint between them for 2/3.
- Use 1/16 marks as reference points to approximate 6/7 by counting down from 1 inch.
7. Practice and Precision
The last trick involves practicing your measurements:
- Develop your eye: Over time, your ability to estimate distances accurately will improve.
- Measure twice, cut once: Even with tricks, always double-check your measurements.
In conclusion, measuring fractions like 2/3 to 6/7 isn't as daunting as it might seem with these simple tricks at your disposal. Not only do they ensure accuracy in various tasks, but they also make your work more efficient.
