Minimum Embroidery Text Size Checker
Is your lettering big enough to embroider?
Letter height × font × stitch × thread × fabric
Lettering built for its real size
Small names, taglines and sleeve text need density, underlay and spacing set for the size they sew at. Hand digitized, checked by a second digitizer, flat price per design.
Everything runs in your browser. Nothing you type is sent to a server.
Enter the capital height, font style, stitch type, thread weight and fabric. The checker says pass, borderline or too small, gives the minimum and recommended heights from Hatch and Madeira figures, tells you what to change, and shows the text on screen at its estimated real size.
What is the minimum embroidery text size?
For a bold sans serif font in satin stitch and standard 40 weight thread, the published minimum is about 6 mm (0.25 in) capital height. Hatch Embroidery lists 6 mm for Tahoma, Verdana and Times New Roman, and Madeira says block letters in 40 weight are about 6 to 7 mm. Scripts need about twice that: Hatch lists 12 mm for Edwardian Script. Finer 60 weight thread lets block letters go down to about 3 mm, Madeira says, and a running stitch font can sew from 4 mm, Hatch says.
The checker works like this:
- Minimum = the published figure for the font style, stitch type and thread weight (table below). Where no source covers the combination, the tool shows a general guidance figure and labels it that way.
- Recommended = minimum + comfort margin (default 1 mm, the width of Madeira's 6 to 7 mm range).
- Textured fabric multiplies both by an extra percentage you can change: 20% on pique or knit and 40% on fleece or terry by default. These are our assumptions; the sources only say to go larger.
- Result: below the minimum is too small, between minimum and recommended is borderline, at or above recommended is a pass.
Worked example (checker output with its default settings): "Jane Smith" with 5 mm capitals, sans serif block font, satin stitch, 40 weight thread on smooth fabric. The minimum is 6 mm and the recommended height is 7 mm, so the result is too small. Three changes each fix it: make the capitals at least 7 mm; switch to 60 weight thread (minimum 3 mm, recommended 4 mm, so 5 mm passes, with a size 65 needle and a file built for it); or switch to a running stitch block font (minimum 4 mm, recommended 5 mm, so 5 mm is a pass).
How to use the checker (step by step)
- Type the text. Enter the name or line of text. It appears in the live preview at its estimated real size.
- Enter the letter height. Type the capital height, the height of a letter such as H, in millimeters or inches.
- Describe the lettering. Pick the font style, satin or running stitch, and 40 or 60 weight thread.
- Pick the fabric. Choose smooth, pique or knit, or fleece or terry. Textured fabrics need taller letters.
- Check the result. Read pass, borderline or too small, with the minimum and recommended heights and whether each figure is published or general guidance.
- Change what you can. Follow the suggestions: larger letters, a bolder font, 60 weight thread or a running stitch font. Copy the link to share the result.
Minimum heights the checker uses
| Stitch and thread | Sans serif block | Serif | Script | Thin or light |
|---|---|---|---|---|
| Satin, 40 wt | 6 mm | 6 mm | 12 mm | 12 mm (general guidance) |
| Satin, 60 wt | 3 mm | 6 mm (general guidance) | 12 mm (general guidance) | 12 mm (general guidance) |
| Running stitch, 40 wt | 4 mm | 6 mm (general guidance) | 12 mm (general guidance) | 12 mm (general guidance) |
| Running stitch, 60 wt | 3 mm (general guidance) | 6 mm (general guidance) | 12 mm (general guidance) | 12 mm (general guidance) |
Published figures come from the Hatch lettering size guide and Madeira's 60 weight thread guide, the same figures as our page on small embroidery text filling in. Hatch also gives a maximum of 6 mm for its run stitch block font, so above that the checker suggests satin. "General guidance" means no source covers that exact combination, so the checker falls back to the nearest published figure rather than inventing a smaller one.
Limits and caveats
- A floor, not a target. The published minimums assume a font built for small sizes and a smooth, stable fabric. Treat them as the smallest you should try, and test sew on the real garment.
- Fonts vary. Two "sans serif" fonts can have very different stroke widths and counters. A condensed or light sans behaves more like the thin style.
- 60 weight needs a matching file. Madeira says to use a size 65 needle, increase density and tell the digitizer which areas use 60 weight. Changing thread on the machine alone rarely gives the full benefit.
- Satin width matters too. Satin reads well only within its width range; see satin vs fill stitch for the limits Wilcom gives.
- The preview is approximate. It uses screen fonts and your screen's pixel density. Calibrate it with the 50 mm bar, but judge real legibility on fabric.

Checked 19 September 2026. The comfort margin (1 mm), the extra height on pique or knit (20%) and on fleece or terry (40%), and the figures marked general guidance are assumptions, not published figures.
