Keep the shape and the physical scale.
Use a clean, high-contrast source image whenever possible. Enter the intended finished width and height, then print at Actual size or 100% so the printer does not silently shrink the stencil.
Thin islands inside letters and shapes need bridges if you plan to cut a reusable stencil. Add those bridges to the artwork before tiling; PageToPoster preserves the source rather than redesigning it.
For a wall or floor stencil, tape the assembled paper to the surface and transfer the outline with graphite paper, chalk, or a pounce wheel before cutting the final material.
