肚子尺寸表! Belly Size Chart!
🕑 Added 2026-02-28 12:00:34 +0000 UTC大家好久不見！二月的我真的是忙翻了，加上農曆新年導致我幾乎月底才有時間畫圖...
自從畫完大家的"角色募集"後，一直很想畫這種肚子尺寸表(belly size chart)，然後就一口氣畫了好多肚子！
並且我想分享一下當時製作時遇到的一些趣事！
當時在畫大家的角色時就為了避免角色們之間肚子大小和寶寶數量不一致的問題，所以製作前就會先將寶寶數量的體積做簡單的計算，來大概知道肚子的直徑大約會多大。
而相同尺寸的肚子反映在不同身高的角色上的視覺效果我覺得非常有趣！甚至自己做了一個計算表格來確保那些大小都能盡量符合真實邏輯而非"憑感覺目測的尺寸"。
而在製作表格時也發現一些有趣的事實：
----
1. 在超妊娠(hyper preg)環境中，每增加一個"足月寶寶(full-term baby)"時肚子的變化會越來越不可見。
因此我製作時的"足月寶寶"其實是大約45個月大而非9個月大的寶寶。
意味著是每次增加一個16~18公斤的寶寶而非3~5公斤的。
而因為"肚子的變化會越來越不可見"，所以在序列圖(progression)中每個階段還會再稍微的提升一點寶寶體積：
-階段1~2維持不變
-階段3提升1.01倍
-階段4提升1.03倍
-階段5提升1.13倍
-階段6提升1.3倍!!
而不同單位的肚子也是按照此基礎去做換算的。
----
2. 腰圍應該和其他肚子單位(belly units)同時存在。
在畫這次圖的時候才想到的，感覺知道肚子裡有多少寶寶的同時能知道她的腰圍是多少那種帶入感會更強烈！
(畢竟每次Funinko在扮孕時都是用量腰圍來判斷自己的肚子有沒有又變得更大)
----
3. 貓醬(CatChan)的腰圍數據被高估了。
因為當時還沒開始畫大家的"角色募集"，所以數據都是憑感覺去寫的。
做了表格後就引起我的好奇：那些數字是否準確？
而答案當然是不準確的，還被高估了！但其實這樣計算後的真實數字也是讓我非常驚訝的！(貓醬也懷得太多了吧!!!)
貓醬的數據也在這次的畫中，自己去揭曉數據吧！
另外這次我還重新畫了"快速虛擬妊娠(Fast simulated pregnancy)"的主角"Day ?? +1天"的模樣，同樣也是非常的巨大！
(但在貓醬底下這尺寸或許成長才剛開始吧，哈哈)

如果你看到了這邊，感謝你喜歡我的這些分享！也歡迎告訴我你的想法~

Long time no see, everyone! I've been super busy in February, and with Lunar New Year on top of that, I barely had any time to draw until the end of the month...
Ever since I finished everyone's character requests, I've really wanted to make a belly size chart, so I just ended up drawing a ton of bellies all at once!
I also want to share some of the fun things that happened while I was working on it!
When I was drawing everyone's characters, I wanted to make sure the belly sizes and baby counts were consistent. So, I did some basic volume calculations beforehand to figure out how big the belly diameter should be.
It's really cool to see how the same belly size looks so different on characters of different heights! I even made a spreadsheet to make sure everything fits actual logic instead of just "eyeballing it."
I also found some pretty interesting facts while putting the spreadsheet together:
----
1. In a hyper-preg setting, adding just one "full-term baby" makes less and less of a visual difference as the belly gets bigger.
Because of that, the "full-term babies" I used for these calculations are actually more like 45 months old rather than 9 months. This means each added baby is about 16–18kg instead of 3–5kg.
Since the visual change becomes harder to see, I slightly increased the baby volume at each stage of the progression:
* Stages 1–2: No change
* Stage 3: 1.01x increase
* Stage 4: 1.03x increase
* Stage 5: 1.13x increase
* Stage 6: 1.3x increase!!
All the different belly units were converted based on this logic.
----
2. Waist measurements should be included alongside other belly units.
While I was drawing this, I realized that knowing the waist size as well as the baby count makes it feel so much more immersive!
(After all, whenever Funinko does her pregnancy roleplay, she always measures her waist to see if her belly has gotten even bigger.)
----
3. CatChan's waist measurement was actually overestimated.
Since I hadn't started drawing everyone's character requests back then, I was just guessing the numbers. Once I made the spreadsheet, I got curious: were those numbers actually accurate?
The answer is definitely no—they were overestimated! But honestly, the real calculated numbers still shocked me! (CatChan is carrying way too many!!!)
CatChan's data is included in this drawing, so go check it out for yourself!
Also, I redrew the "Day ?? +1 day" version of the protagonist from "Fast Simulated Pregnancy," and it's absolutely massive!
(But compared to CatChan, maybe that size is just the beginning, haha.)
----
If you made it this far, thanks for reading! I'd love to hear what you think about all this!

It's a shame girls like this aren't real. But we can always dream.
psychohuh
I would love to see Ilulu at such an immense size!
HUEGH
Ooh, this is a very neat and useful chart! Thank you for sharing this!

哇，也太大了，每個都要再加10倍才行

Is it bad I would love to be size or bigger than catchan?
