Generally, rappelling ropes typically weigh around 55 to 65 grams per meter. Therefore, a 100-meter rope may weigh 5500 – 6500 grams or 12.12-14.33 pounds. Remember, you have to prioritize assessing the strength and weight of each meter of rope before purchasing it. Normally, longer ropes will have more weight, but they are crucial for lengthier rappels.
