Quick Answers
For standard A2 cards (4.25" x 5.5"), you'll need a regular first-class stamp in the US. If your card is thicker or has embellishments, expect to pay extra postage.
Why Card Size Matters for Postage
The size of your greeting card affects both the envelope you need and the postage you'll pay. Standard A2 cards fit in a regular envelope and typically require only a first-class stamp. Larger or oddly shaped cards may be subject to non-machinable surcharges.
If you're unsure about your card's dimensions, check the product description or measure it yourself. Knowing the size helps you choose the right envelope and estimate postage.
Writing Space: What to Expect
The amount of writing space inside a card varies by design. Some cards have a printed message, leaving limited room for your own note. Others are blank inside, giving you full freedom to write as much as you like.
If you plan to write a long message, look for cards labeled 'blank inside' or those with ample white space. For short notes, a card with a pre-printed message may be perfectly sufficient.
Card Quality and Materials
Card quality can affect both the feel and durability of your greeting. Recycled or tree-free papers, like cotton rag, offer a unique texture and are eco-friendly choices. However, they may feel different from standard cardstock and could absorb ink differently.
Consider who you're sending the card to and the occasion. A premium material might be more appropriate for a formal thank-you, while a playful design on standard paper works for a casual note.
Frequently Asked Questions
- What are the common envelope sizes for greeting cards?
- A2 cards (4.25" x 5.5") fit standard A2 envelopes. A1 cards (3.5" x 4.875") require smaller envelopes, often A1 size. Always check the card's dimensions and buy envelopes that match. Measure your card before buying envelopes to avoid mismatch.
- How much postage do I need for a greeting card?
- A standard A2 card in a regular envelope typically requires one first-class stamp in the US. If the card is thicker, has embellishments, or is oddly shaped, you may need additional postage or a non-machinable surcharge. Weigh your card and check with your postal service for exact rates.
- How much writing space is inside a greeting card?
- Blank inside cards offer the most writing space. Cards with pre-printed messages leave less room. If you need to write a long note, choose a blank card or one with a large unprinted area. Read the product description to see if the card is blank inside.
- How can I tell if a card is good quality?
- Look for thick, durable paper, clear printing, and a sturdy envelope. Eco-friendly materials like recycled or cotton rag paper are good indicators of quality and sustainability. Consider the paper weight and material when assessing quality.
