Quick Answer

A standard greeting card for international shipping measures 5 × 7 inches (127 × 178 mm). This size fits most global postal services without extra handling fees. Keep the card flat and use a matching envelope to stay within weight limits.

When you send a greeting card overseas, the dimensions you choose determine whether the item is treated as regular mail or a parcel. Many carriers have a sweet spot that balances cost and handling ease.

Below we break down the most common international standards, explain why a 5 × 7 inch card works for most destinations, and give practical tips for staying compliant.

Key Size Guidelines by Region

North America and Europe generally accept cards up to 6 × 9 inches (152 × 229 mm) before they are classified as parcels. The 5 × 7 inch format stays well below that threshold, ensuring a standard letter rate.

In Asia-Pacific, some postal services limit the maximum thickness rather than size, but a 5 × 7 inch card with a lightweight paper stock usually stays under the 3 mm thickness limit.

  • Measure the card flat, not the folded size.
  • Add a minimum 0.5 inch border for the envelope flap.
  • Check the carrier’s weight limit (often 100 g for letters).

Shipping FAQ Summary

Check Card Dimensions

Confirm the card measures 5 × 7 inches (127 × 178 mm) before ordering envelopes. Ensures eligibility for standard international letter rates.

Select Compatible Envelope

Choose an envelope that adds no more than 0.5 inch to each side and stays under the carrier’s thickness limit. Prevents the item from being re‑rated as a parcel.

Confirm Postal Service Limits

Review the destination country’s maximum weight and thickness for letters. Avoid surprise surcharges or delivery delays.
