To send a picture postcard, choose a format that matches your photo and message: use self-adhesive 4-by-6-inch blanks for a simple photo postcard, or order custom-printed cards when you want a finished design. The Photographer’s Edge pack is best for making postcards from existing 4-by-6 photos, while Per Diem Printing suits personalized occasions. The options below also include bulk custom cards, photo cards with envelopes, and vintage holiday postcards.

Photographer’s Edge DIY Photo Postcards

This 50-pack is best for people who already have 4-by-6-inch photos and want to turn them into postcards. The listed method is simple: remove the adhesive backing and place a photo on the card. The product says no envelope is required and that it meets U.S. Postal regulations.
Choose this option if you want to use your own printed pictures without ordering a custom-printed design. It is also described as suitable for holiday cards or a short personal note. The main limitation is that the photo needs to be 4 by 6 inches, so a differently sized image may need to be resized or printed to fit.
Per Diem Printing Custom Postcards

Per Diem Printing is best for people who want their image, text, or event details printed as a personalized postcard. The listed uses include invitations, announcements, wedding and RSVP cards, baby showers, birthdays, holidays, vacations, and business handouts. Buyers can select a standard postcard backer or a blank backer.
The product is offered in sets starting at 16 cards, with additional quantity options available during customization. The cards are described as fitting A6 or 6-Bar envelopes, which gives buyers an option to mail them enclosed. Choose this product if you want a designed card rather than attaching a photo yourself. Because customization is part of the order, prepare the image and wording before starting the design process.
Bunny Badges Custom 4-by-6 Postcards

These custom postcards are best for buyers who need a chosen design printed on 4-by-6-inch, 16-point cardstock. The product allows customers to upload artwork or add text, including a logo, business details, promotion, personal message, or event information. Listed quantities range from one card to 10,000, making the format suitable for a small design run or a larger mailing.
Choose this option if you want to control the artwork and order a specific quantity instead of using a fixed pack size. It is listed for marketing mailers, event promotions, thank-you cards, invitations, and announcements. A limitation is that buyers need to provide or create the design; this is not described as a pack of ready-made photo postcards.
Silunkia Photo Frame Cards With Envelopes

Silunkia’s 60-pack is best for someone who wants to send a larger 5-by-7-inch photo inside an envelope. The set includes blank white paper frame cards and self-sealing envelopes. The listed frame dimensions are 5.25 by 7.25 inches, and the envelopes measure 5.5 by 7.5 inches. The cards are made from 300 gsm cardstock, according to the product details.
Buyers can print on or decorate the blank cards to create a personalized photo greeting. This is better for an enclosed photo message than for a conventional postcard, since the product includes envelopes. Avoid this option if you specifically need a 4-by-6 postcard format without an envelope.
Vintage Christmas Postcards

This 80-piece set is best for sending seasonal greetings without designing or printing a personal image. The product name specifies 4-by-6-inch Santa postcards and 20 designs, making it a ready-made choice for holiday correspondence. Choose it if variety of Christmas artwork matters more than customizing the picture.
The listed information does not specify the postcard-back layout, writing space, or mailing requirements. Check the card details before writing or mailing, and choose a custom or photo-based option if you need your own picture on the front.
Buying Guide: How To Choose A Picture Postcard
Do you want to attach a photo or order a printed design?
Self-adhesive blanks are a direct option when you already have 4-by-6-inch prints. Custom-printed cards are better when you want text, artwork, or event details incorporated into the design. Confirm the image dimensions and customization steps before ordering.
Should you send it as a postcard or in an envelope?
Choose a postcard format for a direct mail piece, and check that the product provides a suitable back for the recipient address and message. An envelope offers an enclosed presentation and is useful for larger photo cards, such as the 5-by-7-inch Silunkia format. Product descriptions may not provide every mailing detail, so verify the intended format.
How many cards do you need?
Compare pack size with the number of recipients. A 50-pack suits repeated photo projects, while custom options list quantities from small runs to larger orders. For a single seasonal mailing, a ready-made themed set may be more convenient than creating artwork.
What should you write on a picture postcard?
Write a brief greeting or update on the message side, then add the recipient’s complete mailing address in the designated area. Leave the address and postage areas clear. Follow the card maker’s layout guidance, and confirm current mailing requirements with the postal service before sending if you are unsure.
