Mylar Stencil Thickness Guide: 190, 250 or 350 Micron?

Choosing a reusable stencil starts with the design, but thickness affects how the sheet handles. This guide explains the three Mylar thicknesses offered across our stencil range and what to check before ordering.

What does micron mean?

A micron is one thousandth of a millimetre. Our stencil options include 190 micron (0.19mm), 250 micron (0.25mm) and 350 micron (0.35mm). These describe the material thickness, not the size of the design. Check the options on the individual product for availability.

190 micron: the most flexible of these three options

Consider 190 micron when you want a flexible sheet for craft projects or a surface with a gentle curve. Thin material can sit close to the surface, but you still need to secure the stencil and use very little paint. Flexibility does not guarantee that every design will wrap around every object.

250 micron: a middle option

250 micron has more body than 190 micron while remaining thinner than 350 micron. It can be a useful starting point when you want a balance between flexibility and a firmer sheet. Think about the shape of your surface and the detail in the design, rather than choosing solely by thickness.

350 micron: a firmer sheet

350 micron is the thickest of these options. Consider it when you prefer a more substantial sheet for handling and repeated positioning. It will not conform to curves as readily as thinner material. More thickness does not automatically produce a sharper painted edge.

How to choose

  • Check the surface: a flat board and a curved container place different demands on the material.
  • Check the design: fine bridges and small cut-outs need careful handling at any thickness.
  • Check the size: sheet dimensions and the painted design area are not necessarily the same. Read any size information in the listing.
  • Test the technique: secure the stencil, remove excess paint from your brush or roller, and build up light layers.

Do thicker stencils prevent paint bleeding?

Not on their own. Paint loading, pressure, movement and contact with the surface all affect the result. Our step-by-step stencilling guide explains how to reduce bleeding and clean your stencil.

Ready-cut designs or blank sheets?
