How small can embroidery go?
Every shop will tell you a logo is "too small" and none of them will tell you where the line is. There is a line, and it is not a matter of taste: a satin stitch narrower than about 1 mm has no room for a needle in each edge plus thread in between, so it comes out as a dotted line instead of a stroke. That single number decides everything else on this page.
The floor is 1 mm, and it is physical
A satin stitch is thread laid across a shape and caught at both edges. Under roughly 1 mm there is no width left: the two edge penetrations meet in the middle and the stroke reads as a row of dots. No machine, thread or operator gets past this — it is the geometry of a needle, not a setting anyone can turn up.
What that means at a real width
Take a round car badge with lettering inside the ring. At 20 mm across the garment its thinnest line measures 0.32 mm and the small lettering is simply gone. At 30 mm the line is 0.49 mm and the letters break up. At 40 mm, 0.65 mm, readable. At 60 mm the line reaches 0.97 mm — right at the floor — and it comes out clean. The mark did not change; only its width did.
The right fix is the width, not the artwork
When lettering is too thin there are two ways out and only one of them is honest. Making the mark bigger is the whole answer. Thickening the strokes, dropping a word or redrawing a letter is faster, and it hands back something that is no longer the customer’s logo. A badge that has quietly lost its name is worse than one that was never sewn.
- What is the minimum size for an embroidered logo?
- It depends on the logo, not on a rule. Measure its thinnest line: the mark can go as small as the width where that line still reaches about 1 mm. On a typical round badge with lettering that lands near 60 mm across.
- Why does my small logo come out as dots?
- Because the stroke fell under the satin floor. Below roughly 1 mm the needle penetrations on each edge meet, and what should be a solid line becomes a dotted one. The fix is width, not density.
- Can a thin line be sewn a different way?
- Yes — a single running stitch draws a line the satin cannot hold, and that is what the engine reaches for when a shape is too narrow. It reads as a hairline rather than a filled stroke, which is right for a rule and wrong for a letter.
The workshop works the whole mark out on screen at the width you ask for, before you pay. If a line falls under the floor you see it there, not on the garment.
