Introducción
A remittance envelope is the return envelope that carries a payment, a donation, or a completed coupon back to the sender. Its defining feature is a large flap that doubles as a printed surface — the side that faces the recipient when the envelope is opened and that carries the form they fill in.
That design detail is why remittance envelope sizes are not interchangeable with ordinary reply envelopes. The size has to accommodate a coupon or form on the flap, hold the payment securely, and still nest inside the outgoing piece. This guide covers the size family in dimensions only. For the workflow around remittance mail, see our sobres de estado de cuenta y remesa .
What Makes a Remittance Envelope Different
The size decision starts with a structural feature rather than a dimension.
| Característica | Función |
|---|---|
| Large flap | Printed as a form or coupon |
| Remoistenable or peel-seal gum | Seals the payment inside |
| Papel opaco | Hides the contents |
| Often pre-addressed | Returns without the payer writing |
Because the flap carries print, the envelope is specified so the flap is large enough to hold the form — not merely large enough to close.
The Remittance Size Family
Three sizes cover most remittance and coupon applications.
| Tamaño | Dimensiones | Uso típico |
|---|---|---|
| #6¼ | 3½” × 6″ | Compact cash or coupon return |
| #6¾ | 3⅝” × 6½” | Standard remittance, cheque |
| #9 | 3⅞” × 8⅞” | Formato más grande, encaja en un #10 |
A fourth option, the DL format at 110 × 220 mm, serves the same role in A4 paper markets.
| Estándar de papel | Remittance Envelope |
|---|---|
| US Letter | #6¾ o #9 |
| A4 (UK/EU/AU) | DL |
#6¾ Remittance Dimensions
The #6¾ is the default remittance size and holds a standard cheque with the flap open for a printed form.
| Mida | #6¾ Value |
|---|---|
| Ancho | 3⅝” (3,625 pulg / 92,1 mm) |
| Largo | 6½” (6,5 pulg / 165,1 mm) |
| Solapa | Large, printed as a form |
| Acepta | Cheque, cash, small form |
Its proportion is deliberate: long enough to cover a cheque, short enough that the flap uses the full height for print.
| Uso | #6¾ Fit |
|---|---|
| Cheque return | Comfortable |
| Cash donation | Comfortable |
| Coupon return | Workable |
| Multi-field form | Tight — consider #9 |
#6¼ Remittance Dimensions
The #6¼ is the compact option, used where the return form is minimal.
| Mida | #6¼ Value |
|---|---|
| Ancho | 3½” (3.5 in / 88.9 mm) |
| Largo | 6″ (6 in / 152.4 mm) |
| Solapa | Small printed area |
| Acepta | Cash, short coupon |
It suits high-volume, low-complexity returns — a single-line coupon, a cash gift with no declaration field — where the larger #6¾ would waste paper.
| Uso | #6¼ Fit |
|---|---|
| Single-line coupon | Buena |
| Cash gift, no form | Buena |
| Cheque return | Apretado |
| Full declaration form | Demasiado pequeño |
#9 Remittance Dimensions
The #9 is the largest of the family and nests inside a standard #10 outgoing envelope without folding.
| Mida | Valor #9 |
|---|---|
| Ancho | 3⅞” (3,875 pulg / 98,4 mm) |
| Largo | 8⅞” (8,875 pulg / 225,4 mm) |
| Solapa | Full-width printed form |
| Acepta | Payment slip, multi-field form |
Because it fits inside a #10, the #9 supports a bill-plus-return mailing without adding a fold step.
| Factor | #9 Advantage |
|---|---|
| Form area | Room for several fields |
| Nesting | Fits a #10 outer |
| Processing | Fits standard mail extraction |
| Franqueo | Stays inside letter class |

The Large Flap and Print Area
The flap is the structural feature that separates a remittance envelope from a plain reply envelope.
| Flap Spec | Requisito |
|---|---|
| Profundidad | Deep enough to carry the form |
| Gum position | Along the edge only, keeping the form area clear |
| Print zone | Inside the gum line |
| Perforation | Optional tear-off for a receipt |
Getting the gum line wrong is a common specification error, because gum applied across the form area ruins the printing beneath it.
| Error | Consecuencia |
|---|---|
| Gum across the print zone | Form cannot be printed |
| Flap too shallow | Not enough space for fields |
| No clearance from fold | Handwriting runs off the edge |
Fitting a Coupon or Donation Form
The form dictates the size more than the payment does.
| Field Count | Minimum Size |
|---|---|
| Name only | #6¼ |
| Name + amount | #6¾ |
| Name + address + amount | #6¾ or DL |
| Full declaration + signature | #9 |
A practical way to specify is to draft the form first, then choose the smallest envelope whose flap holds it at a writable size.
| Paso | Acción |
|---|---|
| 1 | Draft the form fields |
| 2 | Estimate written field height |
| 3 | Match to the smallest sufficient flap |
| 4 | Confirm nesting in the outer envelope |
Choosing the Right Remittance Size
| Situación | Sobre |
|---|---|
| Cheque return with a short form | #6¾ |
| Cash gift, minimal form | #6¼ |
| Full declaration or multi-field form | #9 |
| A4 market billing | DL |
| Nesting inside a #10 bill | #9 |

Conclusión
Remittance envelope size comes down to three dimensions — #6¼ at 3½ × 6 inches for compact coupon returns, #6¾ at 3⅝ × 6½ inches as the standard cheque and remittance size, and #9 at 3⅞ × 8⅞ inches when the form needs more fields or must nest inside a #10 bill. The DL format at 110 × 220 mm covers A4 markets.
Because the flap carries the form, the size is chosen from the form outward: draft the fields, then pick the smallest envelope whose flap holds them legibly, keeping the gum line clear of the print zone. For the mailing workflow, see our sobres de estado de cuenta y remesa .
