Unfortunately for LEGO model builders, the proportions of the classic LEGO Minifigure are wildly inaccurate as compared to a human. As such, we need to calculate the scaling factor separately based on width versus height. LEGO Minifigure (based on height) Finding the right STL files for 3D printing Lego pieces can be challenging if you’re not designing your own. It retains the familiar shape and dimensions, and once finished, the minifigures are open to painting, drawing, or decorating with decals for the clothes and face to add some personality. It’s motorized and uses a pulley system to really move for that extra realistic feel, and is designed to reach up to around 13 feet, but can be altered to reach as long as you like if you’re dreaming a little bigger. 3D Printed Lego Ferry You could certainly “correct” the LEGO minifigure by lengthening their feet or torso, but you would need to add more than a couple plates to their feet to get it right. I have done the math in the past but do not have it handy now, but I think you need to add 4 or 5 plates to get the height right based on the width, but then the arms start to look ridiculous.

Anyway, using your average of 170 cm for an adult, we get 170/8.98=18.9, or roughly 1:19 scale. If we assume that technic figs represent a 6′-tall person, we’re almost exactly at 1:20 scale. I measured my width at the hips as 40cm (16 inches) which is the value I used in the calculations below. (There isn’t as much data available about average width at the torso or hips as height, but a cursory scan of some sources suggest 40cm is pretty typical across both genders) If you’re looking for more of a scimitar or broadsword, then have a look at this sword collection available to 3D print from one source! Magic WandAmazing resource, best breakdown I found of the scales so far. The only comment I would have is regarding trophyfig/nanofig scale. I feel that given the proportions of a regular lego figure vs a human, it makes a bit of sense to include the plate base of the figure if you’re trying to scale to real world items, since that gets us a little bit closer to human proportions. With that base it gets us to around 106.25 scale, so around 110:1 scale rounded. This is in line with the excellent Saturn V set from the ideas line. I think going with the base or just figure portion would be completely personal preference, and anything ranging from 100:1 up to 140:1 could look about right with the nanofigs. Designed in a 1:1 scale, this Vader piece and accompanying lightsaber are ready to be added to your Lego sets, fitting right in as long as you get your print settings and post-processing right. With an infill setting of 20% and printed in sturdy material like ABS or PLA+, you’ll find this to be a great 3D printed Star Wars model for fans of the franchise and Lego alike. The stud on the top of a Minifigure is ever so slightly taller than the stud on the top of a standard LEGO element. I do not know why, and did not include this subtle discrepancy in my calculations. I encourage you to use these scale calculations as just a starting point for your own modelbuilding – the estimates you suggested seem perfectly reasonable given the latitude for interpretation which is inevitable when working with these tiny scales. Ultimately, if the proportions look good in the finished model, you have succeeded .

Height: 89.8 mm (including nonremovable hair, not including any helmet), or just a smidge over 28 plates tall, but enough less than 28.5 plates that if you stand one in a 28.5 plate-high gap, it looks like there’s a half-plate gap above their head.

I’ve used a different approach to deciding on minifigure scale: deciding that an average door opening is 90cm, corresponding to 4 studs. That gives a scale of 1:28, which fits nicely between the width and length scales for a minifig. Only downside is that building to 1:28 will make the minifigs rather short for their environment.
