The wax seal stamp size guide calculates how many wax pellets you need per seal based on stamp diameter — plus method comparison, sealing temperatures, and tips for crisp impressions every time.
Stamp Details
Common sizes: 25mm (1"), 30mm (1.2"), 35mm (1.4"), 40mm (1.6")
Method Comparison
- • Uses wax glue sticks (not pellets)

- • Good for 10+ seals at once
- • Temp: 250–300°F (120–150°C)
- • Uses pellets or stick wax
- • More control over amount
- • Better detail on intricate stamps
- • Temp: 150–200°F (65–93°C)
Size Reference Table
| Stamp Diameter | Pellets | Best Use |
|---|---|---|
| 20–24 mm (under 1") | 1–2 pellets | Mini envelope seals, gifts |
| 25–29 mm (1") | 2–3 pellets | Standard envelope, invitations |
| 30–34 mm (1.2") | 3–4 pellets | Wedding invitations, cards |
| 35–39 mm (1.4") | 4–5 pellets | Decorative seals, journals |
| 40–50 mm (1.6"+) | 5–7 pellets | Large decorative, gift boxes |
How to Make Perfect Wax Seals
Beautiful wax seals come down to three things: right amount of wax, right temperature, and a cold stamp. The wax seal stamp size guide handles the first — use the method guide below for the other two.
Step 1: Prepare your stamp
Chill the stamp in the freezer for 5–10 minutes before your sealing session. A cold stamp creates a clean release from the wax without sticking. Between seals, keep the stamp cool by pressing it briefly against a cold metal surface or simply waiting 30–60 seconds between impressions.
Step 2: Melt and pour
For pellets: add the calculated number to a melting spoon and hold over a low candle flame or tea light. Stir gently. When fully melted and flowing smoothly, pour onto the surface in one circular motion from the center. The pool should extend slightly larger than the stamp diameter. Let cool 5–10 seconds before stamping.
Step 3: Stamp and release
Press the stamp straight down with even, gentle pressure — don't rock or twist. Hold for 15–20 seconds. Lift straight up. The wax should release cleanly from a cold stamp. If wax sticks, the stamp was too warm or pressed too hard. Practice on scrap paper before stamping your final envelopes.

Is my data safe and private?
Yes. All calculations run locally in your browser. No data is sent to any server.
How many wax pellets do I need per seal?
Standard wax pellets (11mm diameter) fill as follows: 25mm stamp = 2 pellets, 30mm = 3 pellets, 35mm = 4 pellets, 40mm = 5–6 pellets. Pellets compress 50–60% when melted so they fill roughly the area of the stamp. Using too few pellets results in thin edges that crack.
Should I use a glue gun or melting spoon for wax seals?
Glue gun (with wax sticks) gives faster, more consistent results for large quantities — pour and stamp in one motion. A melting spoon gives more control over wax amount and temperature, which produces crisper detail on intricate stamp designs. For beginners, the glue gun is more forgiving.
What temperature should sealing wax be?
Traditional sealing wax melts at 150–170°F (65–77°C). Flexible wax (with adhesive properties) melts at 180–200°F (82–93°C). Never use super-hot wax — it smears rather than stamps cleanly. Let melted wax cool for 5–10 seconds in the pour area before stamping for crisp edges.
How do I prevent the stamp from sticking to the wax?
Chill the stamp in the refrigerator or freezer for 5 minutes before use. Alternatively, breathe gently on the stamp surface before pressing — the slight moisture creates a release layer. For repeated stamping, re-chill between seals. Never press too hard — gentle even pressure makes the cleanest impression.
