# MOO US Print Spec Sheet — six pieces
Prepared 2026-09-14 for upload at moo.com/us (customer: Las Vegas, NV). Every number below was read on a MOO page today unless its status says otherwise. Statuses: **verified** = read on moo.com/us or support.moo.com; **probable** = third-party page, MOO blog, or inferred from MOO's ordering tool; **unverified** = not found. MOO US publishes inches only; every mm figure is a ×25.4 conversion and is marked *derived* unless MOO printed it.

Spot-checked again by me today (fetched live): business-cards/design-guidelines, postcards/design-guidelines, postcards/standard, flyers/design-guidelines, letterhead/design-guidelines, stickers/design-guidelines, stickers/rectangular/vinyl-stickers, coated-paper-stickers 2x3, clear-stickers 3" round, about/printfinity. All researcher figures used below matched, except where noted in the conflict notes.

## 1. PRODUCT-BY-PRODUCT SPEC TABLE

### 1.1 Business card — AVAILABLE AT MOO: yes

**Recommended default: Standard 3.5" x 2" · Original 16 pt · Matte · square corners · landscape.** Why: it is MOO's own pre-selection in the design tool ("Original Paper / Square corners / Matte finish"), the cheapest stock (50 from $23 today), the US wallet/holder size, and the stock Printfinity is available on. Super/Luxe/Cotton/foil change price and artwork rules without changing dimensions.

### 1.2 Flyer — AVAILABLE AT MOO: yes ("Flyers", five self-serve sizes)

**Recommended default: Half Page 5.5" x 8.5" · Premium · Gloss 100 lb cover · portrait.** Why: US half-letter is the standard handout/counter flyer; Premium is MOO's lead stock and Gloss is listed first (100 lb is the heavier of the two Premium options); double-sided at no extra cost; Printfinity available. Pick Premium Matte 80 lb only if the flyer must be written on or glare matters. US Letter 8.5 x 11 is the choice for posters/inserts (row given below).

### 1.3 Vinyl sticker — AVAILABLE AT MOO: yes (two vinyl lines; pick by use)

**Recommended default: Vinyl Stickers (white vinyl) · Large Round 3" · gloss · single-sided.** Why: MOO's only opaque-white vinyl, the only sticker line with Printfinity (up to 12 different designs in the 12-pack), classic brand-sticker size, min 12 from $17. Rated "water-resistant and suitable for everyday handling" — **not weatherproof**. If the sticker lives outdoors/on a car/bottle in Las Vegas sun, switch to **Clear Stickers 3" round** (transparent vinyl, "waterproof, tearproof… outdoors for 6 years… up to 230 °F", one design per order, min 20) — alternate row below.

CONFLICT: the older page https://www.moo.com/us/stickers/design-guidelines says 3.08 x 3.08 | verified (both on MOO) — **3.16 chosen**: the product page, the pixel spec (948 x 948) and the downloadable template all use 3.16 | https://www.moo.com/us/stickers/round/vinyl-stickers · https://support.moo.com/hc/en-us/articles/202941330-Recommended-file-sizes-for-images-photos |

MOO has **no opaque-white weatherproof vinyl**; if that is required, Sticker Mule die-cut vinyl (https://www.stickermule.com/products/die-cut-stickers, **probable**: 300 ppi or vector, CMYK, 0.0625 in bleed if full-bleed, optional magenta 0.05–1 pt cut line, min font 6 pt, min line 1 pt, min 10).

### 1.4 Label — AVAILABLE AT MOO: yes, as sticker SKUs (hub is "Stickers & Labels"; sheets only, no rolls, no custom sizes)

**Recommended default: Coated Paper Stickers · Rectangular 2" x 3" · sheet · one design.** Why: MOO's own pick for labels that meet moisture — "waterproof semi-gloss finish", "easy to write on", recyclable PVC-free paper; 2 x 3 is MOO's name-tag/product-label size; min 20. Use Clear (§1.3 alternate) for glass/plastic containers; Matte Paper is the cheap non-waterproof option.

### 1.5 Postcard — AVAILABLE AT MOO: yes

## 2. PRINTFINITY — rules for a combined multi-business 50-pack

**The shared side must be ONE design for the whole pack: "one side of your product will always be the same — we call it the 'front'"** (https://www.moo.com/us/about/printfinity, verified). Only the other side varies. Both sides cannot vary (vinyl stickers excepted — they are single-sided, so every sticker differs).

For a customer combining several businesses in one 50-pack of business cards this means: **all 50 cards carry the identical front**. Each business can only own a *back*. So either (a) the front is the person — name, phone, email, generic tagline, no single business's logo — and each business gets its branded back; or (b) the front is a neutral monogram/pattern and the Printfinity side is treated as the face (MOO's "front" is simply the first file uploaded; it has no physical meaning); or (c) each business gets its own two-sided identity by ordering **one 50-pack per business** (min 50 each, from $23 on Original today). There is no fourth option.

Decision guide: if every business must show its own logo on the face people see first, place N separate 50-packs. If one shared personal front is acceptable, one 50-pack with ≤ 50 backs, 50 ÷ N each, arriving shuffled.

## 3. UNIVERSAL ARTWORK RULES (apply to all six files)

|---|---|---|---|
| Bleed / safe | **Per product, from that product's moo.com/us table** (corrections adopted; MOO's "2 mm" article is headed for cards). For the six defaults above it works out to 0.08 in (≈ 2 mm) bleed and 0.08 in safe per side; the vinyl 3" round conflict is resolved by building bleed 3.16 / safe 2.84.

## 4. CONFIDENCE — every figure NOT marked verified (carry a "check in MOO preview" note)

Derived (arithmetic from MOO's inch values; not read on a MOO page):
1. Business card trim 88.9 x 50.8 mm (MOO prints only "8.9 x 5.1 cm").
2. Flyer Half Page trim 139.7 x 215.9 mm; US Letter 215.9 x 279.4 mm.
3. Vinyl 3" round 76.2 mm; bleed 80.3 mm; safe 72.1 mm.
4. Label 2 x 3 in = 50.8 x 76.2 mm; bleed 54.9 x 80.3 mm; safe 46.7 x 72.1 mm.
5. Letterhead 215.9 x 279.4 mm trim; 211.84 x 275.34 mm safe; 219.96 x 283.46 mm bleed.
(Postcard Standard 152 x 102 mm IS MOO-published — verified.)

Probable:
6. Rounded-corner radius 5 mm (cards) / 3 mm (MiniCards) — MOO blog only.
7. Flyer landscape orientation allowed — MOO blog; tool toggle unverified.
8. Clear Stickers 3" round bleed 3.16 in / safe 2.84 in / 948 px — read on the Coated Paper article for the same size set; Clear zip not opened.
9. Printfinity uneven split by duplicating a back — inferred from the tool's "Duplicate design" control.
10. Letterhead single-sided = upload front only, skip back — editor not driven.
11. 2 mm cutting tolerance — search snippet of a 404 article.
12. USPS thickness: Original Matte 16 pt = 0.016 in "at the cap" — MOO makes no USPS claim; Gloss 17 pt and thicker stocks exceed it.
13. Sticker Mule specs (alternative printer only) — third-party page.
14. Luxe letterhead "slightly muted" print — stated for Luxe business cards, same paper.

Unverified:
15. How MOO rounds a non-divisible Printfinity split (e.g. 50 ÷ 3).
16. Total ink coverage (TAC) limit — not published anywhere on MOO.
17. Whether the flyer uploader offers a rotate/landscape toggle or needs a rotated file.
18. PDF Upload Tool "Organise Packs" behaviour (gated).
19. Stickers-per-sheet counts for sizes other than 1 x 2.75 (8) and 2 x 3 name tag (4).
20. Portrait rectangular vinyl sticker templates — not documented.

MOO-internal conflicts (both values are on MOO pages; the choice made here and why):
21. Vinyl 3" round bleed 3.16 vs 3.08 in and safe 2.84 vs 2.92 in → build 3.16 / 2.84 (matches template + pixel spec; also satisfies the other page).
22. Flyer US Letter safe 10.8 vs 10.84 in → 10.8.
23. Medium postcard bleed 5.13 x 7.13 vs 5.16 x 7.16 in → not used; match the AI template if ever used.
24. Rack card bleed 3.82 vs 3.83 in → 3.82 (corrections; template = 1146 px).
25. Postcard Printfinity 25 vs 50 → 25.
26. Max file size 50 MB vs 25 MB → stay under 25 MB.
27. Small flyer trim 5.83 vs 5.82 in → immaterial (bleed/safe identical).
28. Standard postcard px 1847 x 1247 (MOO) vs 1848 x 1248 (6.16 x 300) → 1 px, immaterial.
29. Label text minimum 6 pt (return-address/name-tag pages) vs 8 pt everywhere else → 8 pt.
30. Whether displayed sticker/label prices are pre- or post-Q4READY discount — prices are indicative only, promo ends 09/16.
