Why "Satin" isn't the same sheen in every brand

If you’ve ever switched paint brands mid-project and picked the finish with the same name you always use, you’ve probably wondered afterward whether it actually looked the same on the wall. It’s a reasonable thing to wonder — and it’s a real, recurring question across paint forums, not a hypothetical one. Threads on Houzz, PaintTalk, and DIYChatroom all ask some version of the same thing: is Brand A’s Satin the same physical finish as Brand B’s Satin, or Brand A’s Satin the same as Brand B’s Eggshell?

Sheen names are marketing categories, not a shared standard

“Flat,” “Matte,” “Eggshell,” “Satin,” “Semi-Gloss” — every major paint manufacturer uses some version of this ladder, and the names imply a rough ordering from least to most reflective. What they don’t imply is a shared numeric definition. Each manufacturer sets its own gloss-unit range for each name on its own product line, measured with a glossmeter at a fixed angle (see our 60° vs 85° explainer for what that actually means). Nothing requires two manufacturers’ “Satin” to land in the same range, and in practice they often don’t.

This is exactly why GlossAtlas exists: to compare the actual published numbers instead of trusting the name on the can.

Two real examples, worked in full

Rather than restate specific gloss-unit figures here — those live in exactly one place on this site, the data-backed comparison and line pages, so a number is never typed twice and never drifts out of sync with the source — here are two real, worked comparisons that illustrate the point directly:

• Sherwin-Williams Emerald Satin vs. Benjamin Moore Aura Eggshell — two different sheen names, worked against their actual published ranges.
• Benjamin Moore Aura Satin vs. Behr Marquee Satin — the identical sheen name, worked against their actual published ranges.

Look at both pages side by side. The point isn’t which one “wins” — it’s that the sheen name alone predicts neither outcome. You have to check the actual data sheet, for both brands, at the same measurement angle.

What to do about it

If you’re switching brands and want to keep the same sheen you’re used to, don’t shop by name. Use the comparison tool to see which finish in your new brand is closest to your current one by published gloss, and check the full lineup on each brand’s line page if you want to see every option at once. For the full reasoning behind how GlossAtlas builds these comparisons — including why it never converts a figure from one measurement angle to another — see the methodology page.
