Inconsistent scale is one of the main issues with Play Arts Kai figures and perhaps most of us collectors (and interested non- or would be- collectors) usually have questions about which figures are in the same scale (height, bodybuild, head-size?, ahem, etc.). I decided to create this post to help others decide, knowing that there is a considerable number of collectors out there that are very particular with figure scale. For display purposes perhaps? Please feel free to refer to this guide for scale inquiries.
