Toy Making Calculators
Calculators for toy makers and crafters: plush fabric, polyfill stuffing, felt sheets, safety checks, doll clothes scaling, ramps, and production cost.
Materials, scaling and safety checks for handmade toys. 14 calculators, aimed at people sewing plush, turning wooden toys, or costing a small batch for a craft fair.
Choking hazard is the one to run before anything else, and it is built around the small parts cylinder used by regulators: roughly 3.17 cm across and 5.7 cm deep at the deepest point. Anything for under-threes that fits entirely inside that volume fails. The rule catches things people do not expect, including eyes, noses, bells, and a wooden wheel that seemed obviously too big until it went in end-on. The page takes dimensions and tells you which axis is the problem.
Polyfill works from finished volume and a firmness setting rather than a single figure per size, because the same plush stuffed soft and stuffed firm can differ by more than double. Underestimating here is the most common reason a first plush arrives looking deflated.
Doll clothes scaling handles the part that is not simple proportion. Fabric thickness does not scale down, so a seam allowance that works at full size is bulky at 1:6, and the page adjusts rather than dividing everything by six.
Doll Clothes Scaling Calculator
Calculate scale factor and pattern measurements for doll clothes. Enter real-world garment dimensions and doll size to get scaled pattern dimensions.
Felt Toy Material Calculator
Calculate how many felt sheets you need for a toy project. Enter pieces per color, piece dimensions, and felt sheet size to get sheet count per color.
Foam Toy Density and Weight Calculator
Calculate weight and firmness of EVA foam, soft polyurethane, and high-density polyurethane for toy making. Enter dimensions and foam type for grams.
Plush Eye Placement Calculator
Calculate where to place eyes on a plush toy or stuffed animal. Enter head dimensions and pick cute or realistic style for placement coordinates.
Polyfill Stuffing Weight Calculator
Calculate how much polyfill stuffing you need for a plush toy. Enter toy volume and desired firmness to get the weight in grams and ounces.
Pull Toy Cord Safety Calculator
Check if a pull toy cord length is safe per ASTM F963 and EN 71. Enter cord length and target age group to verify compliance with strangulation limits.
Stuffed Animal Fabric Calculator
Calculate how much fabric you need for a stuffed animal. Enter pattern piece dimensions, seam allowance, and fabric width to get total yardage.
Toy Car Ramp Speed Calculator
Calculate the speed of a toy car at the bottom of a ramp. Enter ramp length, angle, and surface friction to get exit velocity in cm/s, m/s, and km/h.
Toy Choking Hazard Size Checker
Check if a toy or part is a choking hazard under ASTM F963 and EN 71. Enter dimensions to see if it fits the small parts test cylinder for under-3 labeling.
Toy Noise Level Safety Calculator
Check if a toy noise level is safe for children. Enter measured dB and distance, then calculate sound pressure at 50 cm per ASTM F963 and EN 71-1 limits.
Toy Paint Coverage Calculator
Calculate how much paint you need for a wooden or foam toy. Enter toy shape, dimensions, number of coats, and paint type to get paint volume in milliliters.
Toy Production Cost Calculator
Calculate total cost and retail price for a handmade toy. Enter material cost, labor time, hourly rate, and overhead for the breakdown and suggested price.
Toy Storage Box Size Calculator
Calculate the box or bin size needed for a set of toys. Enter toy dimensions, quantity, and packing type to get storage volume in liters and cubic cm.
Wooden Toy Dowel Sizing Calculator
Calculate dowel diameter, drill hole size, and blind hole depth for wooden toy joints. Enter wood thickness and joint type for sizing recommendations.
