Did Your Twins Have Almost the Same Weight and Height at Birth?

We wanted to know what the height and weight of twins were during birth.

So we asked our community: Did your twins have the same height and birth weight? What were they?

Here’s what the TwinStuff Community had to say:

Absolutely!! Identical gals
Hannah: 6lbs 5oz; 19 inches
Caitlyn: 6lbs 5.5oz; 19 inches

to receive FREE weekly twin pregnancy updates direct in Facebook Messenger.

And they Battle at every check-up. They go back and forth a quarter of an inch in height and approximately a pound in weight. They are 9 now.

Strangely enough our fraternal twin daughters had the exact weight and length at birth…down to the kilograms! They even measured twice to be sure. Both were 4lbs 9oz., 17 inches long.

My daughter was always bigger they are 22 years old now, he finally grew but she is taller. She takes after her dad, he takes after me.

Yes! Fraternal – 6 lbs, 1 Oz each, 19″ and 19.5″ …they’re 7 now and one is about 2″ taller than the other. One eats everything, whereas the other is picky and clearly it’s obvious who eats better lol the shorter one still can’t get onto most roller coaster/rides because he’s not tall enough

They have always been within an inch in height of each other and still are at 13. Weight has been close but now at 13 and puberty hitting at different times is changing that!

Fraternal girls 31+0 (spontaneous labour). 1560g and 1630g, 0.5cm length difference. They are now 13 and have a 6.5cm and 10kg difference! The older twin (who was smaller at birth) is the smaller of the 2 now. People who don’t know them don’t realize they are twins anymore.

- HW

Not even close! One was 4lb 6oz and the other was 6lbs 10oz. I spent the last month on hospital bed rest because we were concerned about the size difference. Turns out, one is like her 6’ 6” daddy and one is like her 5’ 4” Mama!

My fraternal girls born at 38+2w were the exact same weight and length

Yes, mine did. ID boys. 4lbs 17.2 inches and 4.2lbs and 17 inches. (They were 31 weeks) Now they are 15 years old and one of them is 6.2ft and the other is 6.3ft. The weight is different now due to one playing football and the other volleyball. (My football player is pretty thick, my volleyball player is “softer”)

- CS

Fraternal boys born at 37 weeks. 5lb 12oz and 5lb 2 oz. Stayed closed in size thru the first year. Now at 11 years old one is 103lb and the other is 65. About. 5” difference also. Don’t get asked anymore if they are twins. LOL

Mine were a quarter inch different in height and 8 oz different in weight. The one is still about a quarter to a half inch shorter.

Mine were both 5.8lbs and they’re consistent in staying the same weight or very close to it. One was half an inch taller and they are now pretty much neck and neck.

My twins measured ounce for ounce and inch for inch the same. Baby b (my girl) shot up a pound in 2 weeks while baby a (my boy) only measured a few ounces in the same. They decided to have me deliver at 36 wks 5 days. My boy was 5.13 pounds while my girl was 6.12. They were both the same 19.5”. They are 8 and my boy was 42 pounds while my girl is 64 pounds. My girl also has over an inch in height on him.
