Deformation changes the balance, not only the size.
A smaller copy keeps the same proportions. A deformed character does not. The sculptor Shinya Iguchi describes the work as repeated balance adjustment: simply shrinking something realistic will not produce the Nendoroid form he makes.

Compass Check
Read the proportion change, then check the maker’s word.
Use only to show that proportions can be rearranged. Do not use it to prove Nendoroid’s 2.5-head example, any universal SD ratio, or the appearance of a commercial product.

What is deformation?
Evidence · scope limited
In this guide, deformation means a deliberate rearrangement of proportion used to carry a character into another visual form. The strongest checked explanation comes from practice. Iguchi, a lead Nendoroid sculptor, says that a realistic figure cannot simply be made smaller; different balances have to be adjusted until it becomes that series’ deformation. The maker’s own series page gives one concrete result: Nendoroid describes its figures as about ten centimetres high and 2.5 heads tall. Keep the scope visible. “2.5 heads” is Nendoroid’s self-description, not a rule for every deformed character in Japan.

A small world
Editorial reading
Proportion changes what gets room. A larger head can preserve hair, face, and a recognisable expression while the torso and limbs become shorter. The maker still has to protect pose, costume, and identity; the sculptor describes this as a balance problem rather than a scale operation. That is why two figures at the same height can feel entirely different: one may be a small realistic figure, while the other has been redesigned around a new head-to-body relationship.

Read what changed and what survived.
Evidence · scope limited
First, compare head size with torso and limb length. Second, look for features preserved to keep the character identifiable: hair mass, face, costume, or a signature object. Third, check whether pose and articulation were redesigned for the altered body. Finally, read the maker’s own series name. A cute small figure is not automatically Nendoroid, SD, or any other protected product line.

SD is a recorded label, not one universal measurement.
Evidence · scope limited
Bandai’s archive pairs an SD Gundam character label with the 1986 product name “Gundam Super Deformed.” That is solid first-party evidence for the words inside that product history. It does not establish one head-count, one construction standard, or ownership of every deformed character. Use SD when the work or maker uses it; otherwise describe the altered proportion you can verify.

Official checks
Evidence · scope limited
Good Smile Company is the first-party check for Nendoroid’s 2.5-head description and its sculptor’s process. Bandai’s archive is the first-party check for the recorded SD Gundam product name. Both are commercial sources explaining their own lines, not neutral dictionaries for all character art.
