The Swedes keep all this on record for stallions in Sweden, and you can find out which stallions tend to increase or decrease height.I seem to remember Amiral decreased height by maybe an inch…I have an Amiral son, and my stallion is 16.2 H but seems to add 2 to 4 inches to smaller mares.
AND the Braveheart babies seem to grow forever, so you’ve got a double whammy! I keep hoping mine will stop soon (rising 5), and just get laughed at by other people with BH babies… :uhoh:
ETA: I’ve just realized this is a super old thread. How big is he these days??
I bought a G-Line mare advertised as 15.2 as a 4 year old. She’s now 7.5 years old and an honest 15.1!
Perfect Pony, they probably told you how much more she was going to grow at four too, right? LOL! I think these stories are much more common than the late growing ones, unfortunately.
Of course! She did look like a 2 year old at 4, and just about EVERYONE told me she would grow. Her sire is 16.2+, dam was about 15.2-15.3 but all her half siblings were over 16 hands.
She was supposed to be 15.2 and end at least 15.3-16 hands. Funny thing is, she now measures 15.1 with shoes on. She did look about 15.2 to me when I bought her, I have since learned that almost every horse is over measured by an inch or three! A TRUE 16.2-17 hand horse is HUGE.
Maresnest…I did something similar, bred my 15.3H to a 16.3H stallion. Resulting filly is coming 3 and is already 16.2H. Guessing she will end up 17.1H. Who knew!
I am wondering this too! Sounds from these replies there are no hard, fast rules on what size they end up. My friends horse (oldenburg/Tb) did keep growing until age 7. Really filled out and grew probably an inch in height after age 5.
I have my first youngster and am wondering where she’ll end up (Trak/Tb cross). The stallion is 16.1 and the mare was big (over 16h–but don’t know exact height). My filly is 3 years old and in October was 15.2 and 1/2 
hands. Now she seems to be growing a bit (she’s in regular work now) and is at 15.3. I am crossing my fingers that she ends up at 16 (I don’t need a big horse–I am small). But my other mare is 16.1 and I’m used to that size.
What is the string test? How do I do it?
Explained within this thread. Two types of string tests – one measures from mid knee to coronary band (if measurement is 16 inches, supposed height is 16H) and the other from ergot to point of elbow, then release string at ergot and pivot string up from elbow to eventual (supposed) height.
Since this is a three year old thread everyone should come back (that was guessing their horse’s height) and state what ended up happening.
I wasn’t on original thread - but of my babies that I kept or knew until adult, none where straight WB, so that might affect my results! but -
16.3 ISH to 16.3 TB = 15.2 yearling = 15.3 3yr old = 16 h mature
16.2h TB to 15.2h TB = tall weanling = 17h solid 4 year old
16.3 WB to 15.2h TB = 15h yearling = 15.2 h 2yr = 15.3 h 3yr = 16h 4 yr = 16.1 mature
16.2 WB to 16.2 TB = 16.1 yearling = 16.2 2yr = 16.3 3yr = 16.3 3/4 mature
NONE of the string tests were even close on any of these horses. The ones that looked the most gawky as yearlings and 2 year olds were the biggest. The ones that were the most filled out, roundest rear ends etc. ended up the smallest.
My friend who is LONG legged needs a big bodied horse who is also at least 16.2 - she just bought a 2 yr old, who is now 3 coming 4. Was a big 2 year old - 16h… he is still 16.1… He is WB/QH/TB - I hope he pops up!!
They do fill out a shockig amount though. A true 16.2h horse is a great size - once they fill out!
