Why does a drafting pencil have a 4 mm sleeve?
A long, thin sleeve lets you see the line you’re drawing and keeps the tip flat against the edge of a ruler or template. STAEDTLER Japan says the 4 mm sleeve gives a wider view and sits closer to the ruler.
The pencil is balanced low, the maker says, so it stays steady over long sessions. The same idea runs through other drafting pencils such as the rOtring 600 and the Pentel Graph 1000 for Pro.
Which lead size should you choose?
Pick 0.5 mm for general writing and drawing, 0.3 mm for fine technical lines, and 0.7 or 0.9 mm if you press hard. The 1.3 and 2.0 mm versions are for sketching and bold lines.
Each size has its own colour code. Use any good lead of the matching diameter; STAEDTLER’s own Mars micro carbon is one option, and Pentel Ain Stein is another.
How does the 925 25 compare to other drafting pencils?
It’s lighter than the all-metal rOtring 600, costs less, and comes in more lead sizes than either pencil below.
| Pencil | Body | Weight | Lead sizes | Price band |
|---|---|---|---|---|
| STAEDTLER 925 25 | Aluminum | 17 g | 0.3–2.0 mm (6) | $$ |
| rOtring 600 | All metal, hexagonal | about 22 g | 0.5, 0.7 mm | $$$ |
| Pentel Graph 1000 for Pro | Plastic, metal tip | about 11 g | 0.3–0.9 mm | $$ |
STAEDTLER Japan also sells the night-blue 925 35 and an all-black 925 35 version, which share the 143 mm body. Our best mechanical pencils roundup lists alternatives at every price.

Frequently asked questions
Is the Staedtler 925 25 all metal?
The body is aluminum, per STAEDTLER Japan, and the clip, grip and sleeve are metal too. It weighs 17 g, light for a metal pencil.
What's the difference between the Staedtler 925 25 and 925 35?
The 925 35 is the night-blue version STAEDTLER released in 2010 for the 925 25's 20th anniversary. STAEDTLER Japan lists the same 143 mm size and 17 g weight, in five lead sizes instead of six.

Yes. STAEDTLER Japan lists a window that shows the lead grade, and the line width is colour-coded and printed on the pencil.
What eraser refill fits the Staedtler 925 25?
The 92R, according to STAEDTLER Japan. It doesn't fit the 1.3 mm and 2.0 mm versions.
Is the 925 25 good for writing, not just drafting?
Many people use it for notes. Its 4 mm sleeve and fine lead are built for drafting, but at 17 g with a knurled grip it is also comfortable for long writing.
Is the Staedtler 925 25 made in Germany?
No, retailers say Japan. STAEDTLER is a German brand from Nuremberg, but the 925 25 carries a Japanese barcode and is sold by STAEDTLER Japan; the maker's page doesn't state the country.
