Guide to Ball Jointed Doll

Why hello there, are you interested in ball jointed doll?
Or a first timer perhaps and you want to know more about ball jointed doll or as we all know as BJD?

As we are also a bjd/doll enthusiast, we decided to compile these information together for your reading pleasure into understanding BJDs.

What exactly is BJD?

BJD or known as Ball Jointed Dolls are dolls that is articulated with ball and socket joints. Basically, these mechanism allows them to move. Modern BJDs often has the characteristics influenced by both realistic and to those of anime (japanese animation style). Thus why they are widely popular to doll enthusiast.

They commonly range in size from about 60 centimetres (24 in) for the larger dolls, 40 cm (15.5 in) for the mini dolls, and all the way down to 10 cm (4 in) the very smallest BJDs. BJDs are primarily intended for adult collectors and customizers.

They are made to be easy to customize, by painting, changing the eyes and wig, and so forth.

How big are they?

They have a couple of different size, if you had noticed our website’s doll listing.

Simply put here is the measurement and its size names:

  • 70cm / SD17 – 70cm+ in height
  • 1/3 / SD – 60-50cm in height
  • 1/4 / MSD – 40cm in height (sometimes they can go up to 48cm in height)
  • 1/6 / YOSD – 20-30cm in height
  • 1/12 Tiny – 10-18cm in height


Ball-jointed dolls are initially modeled in clay, commonly polymer clay. The hardened clay body parts are used to form molds for multiple parts to be cast in synthetic polyurethane resin. Cured resin has a hard, smooth, porcelain-like feel, but is less brittle. Unlike porcelain however, polyurethane tends to turn yellow and decay over time depending on exposure to UV light and heat. The resin casting process allows for molds to be produced with a relatively low initial investment, compared to the injection molding commonly used for mass produced vinyl dolls. However, the materials are more expensive, and the process requires more manual labor, resulting in a higher cost per unit.

How to care for BJD?

Caring for BJD is simple.

Simply do not soak them on water as their metal hook parts can rust if they are not dried properly. Do not expose them to lights or the sun too much for a long period of time as they can yellow over time. Make sure that they are not placed in damp environment for a long period of time as well in fear of moss or fungus growing on them.

If you don’t like keeping your doll childrens inside their box, remember to always brush dusts off their face and body as they can stick if left for a long period. If you bought them a new set of clothes, remember to wash the clothes first to prevent the colour of the clothes staining the doll’s body or face.

Last of all,

Just remember to just have fun with them, and no we don’t mean wrestling with them.
All in all, dolls are a special, there is no such thing as an ugly doll. If you like them, then like them without having people telling you so.

BJD collecting is a hobby where you let your heart decide.
