Whether I’m sending out invitations, greeting cards, or promotional materials, these envelopes have become a staple in my stationery collection. Here’s my comprehensive buying guide to help you find the perfect 4.25 by 5.5 envelopes.
Understanding the Size
The 4.25 by 5.5 envelope size is also known as A2 size, which is a perfect fit for standard invitations and small cards. I’ve found that this size is ideal for many occasions, from wedding invitations to thank-you notes. Before buying, I recommend measuring your cards or documents to ensure they fit snugly.
Material Matters
The material of the envelope can significantly affect its look and feel. I’ve encountered various options, including:
- Paper: Standard paper envelopes are lightweight and economical. They’re great for everyday use, but I usually opt for heavier paper for more formal occasions.
- Cardstock: For a more premium feel, cardstock envelopes provide sturdiness and a professional touch. I love using these for special events.
- Padded: If I’m sending something delicate, padded envelopes offer extra protection. Although they’re bulkier, they give me peace of mind.
Closure Types
I’ve noticed that envelopes come with different closure types, and this has impacted my choices:
- Self-Seal: These are my favorite! They save time and require no extra glue. Just peel off the strip, and I’m good to go.
- Moisture-Seal: These traditional envelopes need a lick to seal. I find them reliable, but I prefer self-seal for convenience.
- Peel and Stick: Similar to self-seal, they have a protective strip that I peel off. I like the ease of use these offer.
Color and Design Options
I appreciate that 4.25 by 5.5 envelopes come in a variety of colors and designs. From classic white to vibrant hues, I can choose based on the occasion. For formal invitations, I typically stick to neutral colors, while I let my creativity flow with fun patterns for casual invites.

When I buy envelopes, I often consider the quantity I need. It’s usually more economical to purchase in bulk. I’ve found packages ranging from 25 to 500 envelopes, depending on my needs. If I’m preparing for a big event, I’ll go for larger packs to ensure I have enough on hand.
Price Range
The price of 4.25 by 5.5 envelopes can vary widely based on material, quantity, and brand. During my shopping experience, I’ve seen prices range from as low as $5 for basic packs to $30 or more for premium cardstock options. I always recommend comparing prices across different retailers and looking for deals, especially when I buy in bulk.
Where to Buy
I’ve discovered several places to purchase these envelopes:
