What Size Is a Regular Greeting Card? Gift Card Dimensions, Frame Standards, and More

One thing five years of corporate purchasing has taught me: the word "standard" does a lot of heavy lifting in product descriptions. Standard gift card dimensions, standard greeting card sizes, standard picture frame sizes. They sound like universal answers, but the right size changes depending on what the item is for and who's receiving it.

I manage procurement for a mid-size professional services firm—about 60–80 orders a year for gifts, event supplies, and team engagement materials. Dimensions have caused more missteps than pricing or lead time ever did. So here's how I now think about sizing: not as a single list of "correct" numbers, but as three different scenarios.

Three Scenarios, Three Sets of Rules

The mistake I made early on was looking for one answer. "What size should we order?" depends entirely on what you're ordering and what the recipient will do with it.

• The hand-it-once gift — gift cards, greeting cards. The item is a vehicle for a message or value, and it gets used quickly. Standard dimensions reduce friction; unusual dimensions add cost and confusion.
• The put-it-on-display gift — picture frames, décor, keepsakes. The item sits somewhere visible. The dimension has to fit a desk, a shelf, or a wall, and it says something about your company every day the recipient sees it.
• The do-it-together gift — paint by number kits, diamond painting. The item is an activity. The dimension determines the time commitment, which is a bigger deal than the final piece's size.

If you're ordering any of these in bulk for clients, employees, or events, your next step depends on which scenario you're in.

Scenario 1: Gift Cards and Greeting Cards

What size is a regular greeting card?

In the corporate world, the most common greeting card size is 5 by 7 inches when folded (so it opens to 7 by 10). That's the size you see in most promotional card lines. But it's not the only "standard." A2 cards, which measure 4.25 by 5.5 inches, are the default for short notes and invitations, and A6 cards (4.5 by 6.25 inches) are common for thank-you cards. The "regular" size really depends on the printer, so always ask for the specific dimensions before approving a proof.

Greeting card size also affects postage. If you're mailing cards in bulk, the USPS letter requirements apply (Source: usps.com). A First-Class letter must be 3.5 to 6.125 inches high, 5 to 11.5 inches long, and no more than 0.25 inches thick. Larger envelopes count as flats, which cost more. That's why we keep most of our corporate cards in the A2 to 5x7 range—they fit in standard envelopes without turning into an expensive mailpiece.

Standard gift card dimensions

Gift card dimensions follow the CR-80 standard: 3.375 by 2.125 inches, about 0.03 inches thick. That's the same size as a credit card, and it exists so the card works in standard readers, wallets, and card mailers. When you're buying 500 or 1,000 cards, staying at CR-80 means you can use inexpensive standard envelopes and your recipients can actually put the card in their wallet.

Here's something vendors won't tell you: the card dimension is rarely the point of failure. The packaging is. We once priced a custom gift card shape that was only slightly larger than CR-80. It looked great in the mockup, but it required a custom mailer. At 1,000 units, the per-piece cost went from about $0.12 to $0.65—an extra $530 on packaging alone (pricing based on supplier quotes, January 2025; verify current rates). That's a great example of why I always test the complete package, not just the card, before approving an order.

If you're buying from a supplier that handles both products and packaging, ask for the full assembled dimensions—card, insert, envelope—before you commit. This is one of those things that feels like a detail until it's a budget line item.

Scenario 2: Picture Frames

Picture frame dimensions are trickier because "5x7 frame" doesn't mean the frame is 5 by 7 inches. It means the frame holds a 5 by 7 photo. The outer dimensions are bigger. That distinction matters if you're ordering frames as corporate gifts and you expect them to sit on a desk or shelf.

The most common photo frame sizes in the US are:

• 4x6 — small tabletop, often used for desk photos
• 5x7 — the standard for a single desk photo
• 8x10 — the largest size that still feels natural on a desk or cubicle shelf
• 11x14 and up — these are wall pieces, not desk items

Here's the counterintuitive part: if you're giving frames as gifts, don't size them for the photos you assume people will print. Most people don't print photos anymore. They scroll. When we ordered custom frames for our annual leadership summit, the first batch sat empty on desks for months. The second batch solved the problem by shipping each frame with a ready-to-insert card—a branded thank-you note sized to fit. That made the frame a finished gift instead of homework.

This is also where I'll admit to having mixed feelings about mats. On one hand, a mat makes the frame more versatile because it can hold different photo sizes inside the same outer frame. On the other hand, it adds inventory complexity and a slightly more delicate product to ship. If you're ordering a mix of recipients and don't know what they'll display, a frame with a premade mat is the safer call. If you know exactly what's going in it, skip the mat and keep the profile slim.

And a word on size and perception: the first physical impression the recipient gets is the size and weight of the package. A frame that's too small to hold its place on a desk gets pushed aside. A frame that's clearly too big for the space ends up in a drawer. Neither one says "quality gift."

Scenario 3: Paint by Number and Diamond Painting Kits

If you're searching "dimensions paint by number," the numbers in the product titles are usually the canvas dimensions: 16x20, 20x24, 24x30 inches. What those numbers don't tell you is the time commitment, and that's the dimension that actually matters for a team activity.

A 16x20 canvas generally takes 10–15 hours to complete. A 24x30 can take 30 hours or more. If your goal is a shared team event, a larger canvas doesn't make it better—it makes it longer. I've seen teams start a large kit together and lose momentum before finishing, which is a worse experience than completing a small kit and feeling good about it.

Diamond painting kits come in slightly different sizes, and this is where units get confusing. Many diamond painting kits are listed in centimeters, not inches. A 30x40 cm kit is roughly 12x16 inches. A 40x50 cm is about 16x20 inches. If you're comparing suppliers, make sure both are quoting the same unit, or you'll get a very wrong idea of scale.

What most people don't realize is that listed kit dimensions often refer to the full canvas, not the finished artwork. Some kits include a printed border that gets trimmed or stretched, and nobody flags that in the product title. When you're evaluating a kit, look for the "finished size" or "painted area" spec. It can be a couple of inches smaller than the canvas, which changes how it feels once it's mounted.

For corporate gifting, I'd rather order smaller kits with good color coverage and clear patterns than huge kits that promise a masterpiece but demand 40 hours. A kit that gets finished is a better brand impression than one that becomes a folded-up reminder of an unfinished obligation.

Which Scenario Are You In?

Here's the practical test I use when someone asks what size to order:

• Will the recipient use it within a minute of opening it? Then default to standard sizes. Gift cards at CR-80, greeting cards at A2 or 5x7, and premium packaging only if you've confirmed the budget covers it.
• Will it sit on a desk, shelf, or wall for months? Then think about the physical space, not the category standard. Choose a size that fits the setting, and make it display-ready with an insert or mat.
• Will it be an activity that takes time to complete? Then size equals commitment. Ask what the actual finished size is, estimate the hours, and choose the smallest version that still feels meaningful for the group.

Three questions to ask any supplier before approving an order:

1. What exactly is being measured—the product, the packaging, or both?
2. Does this size fit standard mailing and shipping constraints, or will it incur surcharges?
3. What's the finished dimension after trimming, matting, or mounting?

Getting the answer right is not about memorizing a chart. It's about deciding what the recipient should experience. When the dimension matches the situation, the item doesn't just look better—it respects the recipient's space and time. And in a corporate gift, respect is the message that lasts longer than the product.
