Sixth scale is older than most collectors realise. Its story runs in two great arcs: the classic toy era that invented the format, and the modern premium era that turned it into a collector's art form. Here is the short version.
The format begins with G.I. Joe in 1964, the toy that coined the term "action figure" because the makers refused to call a boys' toy a doll. At roughly 12 inches it set the 1/6 standard that survives to this day.
Across the Atlantic the same body became Action Man, and the era was defined by soldiers, adventurers, and an endless run of uniforms, weapons, and accessories. The adventure-and-equipment format was born here, and 1/6 has never fully let it go.
Then came Star Wars, and the toy aisle shrank. The 3.75-inch figure became the dominant scale because it let kids buy whole armies and playsets cheaply. Twelve-inch figures lost their mainstream toy dominance and faded toward the margins.
1/6 did not die, but for over a decade it was no longer where the action, or the money, was.
The revival was driven not by kids but by collectors. A 12-inch resurgence took hold, Sideshow began its rise, Medicom was founded in Japan, and a distinctly Japanese, pop-culture-driven take on 1/6 started to emerge.
For the first time the format was aimed squarely at adults who wanted accuracy and display value, not playground durability. The groundwork for everything that followed was laid in this decade.
This is the hinge of the whole story. Hot Toys arrived, Sideshow secured Star Wars, Medicom built out its Real Action Heroes line, and brands like Enterbay pushed realism further. Military accuracy and the first serious movie figures set a new bar.
Sixth scale stopped being a nostalgia niche and became a premium format: better sculpts, real tailoring, and the beginnings of the cinematic likeness race.
The Marvel and Star Wars booms turned 1/6 into a juggernaut. Hot Toys defined the decade with diecast armours, deluxe editions, and an ever-expanding licence list, while Sideshow's distribution put those figures on shelves worldwide.
Crucially, this is also when the third-party and specialist scene exploded, filling every gap the big licensees left open. The catalogue became deep enough to be worth cataloguing.
The current era is about craft at the top end. InArt and Artisan-tier releases brought rooted hair, glass eyes, and hyper-realism, alongside higher prices and premium packaging. A mature third-party ecosystem now rivals the majors on quality.
Sixth scale has come full circle: from a children's toy that invented a category, to a collector's medium chasing the most lifelike miniature figures ever made.
