At 20 weeks pregnant, the baby is about 6 to 6.5 inches (approximately 16 cm) long from crown to rump and weighs around 10 to 11 ounces (about 320 grams)
. This size is roughly comparable to a banana or a sweet potato
. Starting around this time, measurements may also be taken from head to heel, which can be about 25.6 cm (10 inches), but crown-to-rump length is more commonly used at 20 weeks
. The baby is becoming more active, with muscles growing quickly, and may even start sucking their thumb
. This is the halfway point of pregnancy, and the baby still has significant growth and development ahead.
