Most toddler stencil sets are made from plastic or from cardstock/paper.
Sizes range from small tracer stencils around 8" x 6" up to larger cut-outs about 19.5" x 12", with some kits offering intermediate dimensions.
Many listings include CPSC choking-hazard warnings for small parts; some kits also note non-toxic materials or compliance with safety standards.
Some stencil kits are designed to align with standard letter-size paper (8.5" x 11"), and several listings recommend using the stencils on paper.
Most listings suggest starting around age 3; some specify ranges like 3–10 years, and others note 4 years and up.
Common shapes include basic geometric templates (circle, square, triangle), people and animal figures, and learning shapes such as letters and numbers; some sets also include themed motifs like outer space.
Kits commonly include coloring pencils or washable markers, printed or sticker paper, and pencil sharpeners; some also include scissors, a travel case, or an alignment base board with clips.
Helpful features include large, simple shapes sized for little fingers, sturdy/thick plastic stencil sheets, and alignment aids such as a base board with clips or non-slip alignment for standard paper sizes.
