Only after I submitted did it occur to me that the size could be similar to the moon's
As someone not very up-to-date in Web UI techniques, I was curious as to how the array was being advanced on scroll. Unfortunately, it looks like the answer is basically polling. The code constantly calls window.requestAnimationFrame(), checking window.pageYOffset. This means that the page is constantly doing work, even at idle.
Surely the more correct way is to install an onscroll handler or something, right?
Might as well say “shuffled emojis with random data attached”
But if you use a more typical domestic goat, like an Irish Goat, you get a height of 80-90cm. The length is even longer.
But what really bugs me is that it simply uses some font it finds on your system, so on my slightly outdated Linux version it only shows about 70% of the emojis. I mean, if there was ever a perfect use case for webfonts, it would be this page...
His cow is about the average total height of a cow at 160cm.
He has an oddly short man though at 165cm / 5'5".
And he says the horse is the same size, but that would be only 16 hands. That would be the withers size of an average horse, but the total height of only a pony.
In anatomy, the arm is the part between the elbow and the shoulder.
Below the elbow is the forearm.
With that in mind, 30cm for the arm is definitively a sound measure... and the name of the emoji is wrong. On every phone, keyboard and app.
tl;dr; what is commonly called arm is in fact arm + forearm. Don't blame the author for being correct.
And every popular implementation shows arm + forearm + fist.  Giving only one part of that as the length is just wrong.
Even if it were called arm, I would argue that that should be shoulder to wrist, since that's what commonly called an arm. It's also the definition that Merriam Webster has. 
I was just annoyed that GP seemed to diminish OP's efforts in building their page by nitpicking chosen lengths and terms, and I chose to enter the game rather than nothing.
Your comments are welcome and informative, thank you for that.
Dictionaries are descriptive and not normative, which confirms the common use of arm as "wrist to shoulder".
Great. Since that's actually what it means, in ordinary English. What you call "actually correct" "in anatomy" is professional sub-language and has no bearing on this forum. (Or any other, besides fora for professional anatomists.)
Edit: Sorry, replied to your first paragraph before even reading the rest and noticing that you actually agree... I was already slightly annoyed by your previous post, so wrote hastily. I apologize.
Back then the supplier of the websites also made the phones, and you could only access specific mobile webs depending on your carrier.
The original emoji were mostly create to facilitate online shopping for train tickets for vacation and ringtones. So a lot of these represent travel, food and landmarks.
Edit: this is for Japanese handsets and carriers. That was pretty unclear before the edit
The Wikipedia page of the creator has some links to the origin story:
How come a real-time 3D rendering is faster then just displaying a few 2D pictures side by side on a screen? Tech these days is weird.
- A chicken egg is taller than 5cm.
- I would say a tulip is bigger than a phone.
- The okay hand sign says it's 21 cm.My hands are larger than average, but definitely smaller than 21cm.
- A duck isn't bigger than a goat.
- An elephant is smaller than a house.
"duck height": 20 – 30 in (51 – 76 cm)
"goat height": 16 – 23 in (40 – 58 cm)
Maybe it would be better to do them by mass.
It would have made more sense to stay with either height or the largest dimension (but that would have been weird for mountains, which often are far wider than high).
Very cool project tho!
When you say "far larger", is that twice as big? 10 times bigger? 1000 times bigger? I might have to avoid where you live.
There's more of these which are really weird, like the 12m cactus.
I thought this was a mistake but it checks out.
They even have 6 flags on the stadium ( which I'm assuming is a reference to Six Flags over Texas, could be wrong though) but no baseball field?!?
Awesome project OP!
V2 should try everything by mass.
What is the biggest size jump in this database by percentage growth between one emoji and the next?
Curiously, a map is not this size, Japan is. A map is closer to 1m.
Instead of careful and clarity in writing, people choose Emoji to respond to what needs to be more clarified.
So, if it's hard to express your thought, let's pick an Emoji!?
At work, this leads to more trouble in writing. Most of JIRA tickets are mostly non-existent that it's badly written, confusing to the developers and rest of the team.
Emoji might be just one reason for that. But anyway, it just shows the trouble on how people have problem in writing communication.
Do people overuse Emoji ? I don't think this is about overuse or not, it's about people failed at expressing their thought through writing.
Not all responses between humans need to be written in prose. Using images has been and will continue to be a significant way for humans to communicate with.
