Size of Yujin figures?

Hello, I would like to know the exact size of this figure in cm. I've seen for sale in an eBay shop that indicates approximate size, sometimes in cm, sometimes in inches, and sometimes indicating two very different sizes in two parts of the item description, so I don't know what will be.

Yujin Crab Gashapon Capsule "Birgus Latro"
Site indicates "Around 4 cm". A bit too large, but still acceptable... Are there some smaller but equally accurate figures of coconut crab easily available in any other brand?

My figure is packed away at the moment but 4.0 cm would be the total length or legspan, not carapace width. The image below are the four figures of B. latro. All are probably too big for your scale range,but the smallest (the Kaiyodo Okinawa figure) might work (number 3). However it is very rare and hard to come by.

I believe to large for your taste :)

Thanks! If it measures 4 cm of total lenght including antennae, then is perfect for me. If it's legspan in width (not lenght) is a bit large but still works. THe Yujin coconut crab is only slightly larger than the Kaiyodo one according to your comparison picture, and both are more accurate than the other two, too large figures.

So, the Yujin figure measures exactly 4 cm lenght, including antennae?
Then, I will go for it :)
