So like the size of a horse?

The average horse is about half the height and weight of the average giraffe. Giraffes are just a really bad unit of measurement, males weight about 400kg more than females and there is a wide height difference over their global population, they are technically four different species we just all call giraffe 🦒

In other words, a large boulder the size of a small boulder

Even if you think height divided by two, why even describe it that way? Giraffes are tall, but not so unfathomably tall that something half its size is incomprehensible. That’s 7-9ish feet. You couldn’t say the size of Andre the Giant?
