The device that a tailor should use to measure the length of cloth is a measuring tape. A measuring tape is a flexible, long strip of material, usually made of cloth or metal, with linear measurements marked along its length. It is an essential tool for tailoring as it allows precise and accurate measurements to be taken.

**Importance of Measuring Tape in Tailoring:**

1. **Flexibility and Versatility:** A measuring tape is flexible and can easily be wrapped around curves, corners, and contours of the body or fabric. This makes it suitable for measuring various body parts and fabric lengths.

2. **Accurate Measurements:** Measuring tapes are marked with linear measurements in inches, centimeters, or both. This allows tailors to measure fabric lengths accurately and ensures that the finished garment fits properly.

3. **Easy to Use:** Measuring tapes are user-friendly and do not require any special skills to use. Tailors can simply extend the tape, place one end at the starting point, and read the measurement at the other end.

4. **Portability:** Measuring tapes are lightweight and compact, making them easy to carry around. Tailors can easily take measurements on-site or when working with clients outside their shop.

5. **Precision:** Measuring tapes often have markings in small increments, such as 1/8 or 1/16 of an inch, allowing for precise measurements. This level of accuracy is crucial in tailoring to ensure a well-fitting garment.

6. **Durability:** Measuring tapes are designed to be durable and withstand regular use. They are made from materials that can withstand wear and tear, ensuring their longevity.

7. **Cost-Effective:** Measuring tapes are relatively inexpensive compared to other measuring devices, such as measuring rods. This makes them accessible to tailors of all budgets.

In conclusion, a measuring tape is the ideal device for tailors to measure the length of cloth. Its flexibility, accuracy, ease of use, portability, precision, durability, and cost-effectiveness make it an indispensable tool in the tailoring industry.

Tailor use measuring tape because tailor can't use scale, string and measuring rod to measure clothes
