Hey there, if you’ve ever stared at a product on a shelf for too long (guilty, I’ve definitely wasted way too much time debating whether that energy drink is worth grabbing vs. the one next to it) and thought, “That card packaging looks off,” same. As a packaging card supplier, I’ve seen so many brands drop the ball on design that they swear’ll sell their stuff, only to realize half their flaws are so fixable it feels like cheating. I’ve been in this game for 7 years, worked with every size brand—from random local candle makers to mid-sized tech accessories folks—and today I’m spilling the tea on the most common mistakes I see, plus little fixes that actually move the needle. Packaging Card
First up: skipping shelf clarity like it’s a viral tweet that’s been buried. Wait, let’s unpack that. Most brands design their card packaging to look good on their laptop screen, not in a grocery store aisle that’s got harsh overhead lights, or a boutique where someone’s browsing while scrolling TikTok on their phone. For example, last year a startup selling wireless earbuds sent over a design that had their logo in a tiny script font, and their key selling point—“24hr battery”—was tucked into a corner next to a QR code for a manual. When we mocked it up in actual retail packaging, I told them straight: “No one’s gonna stand there holding their phone to scan that while 10 people are waiting in line. Also, your logo is so thin it blends in with that light gray background.” They went back, blew up the logo to take up the top 15% of the card, made “24HR BATTERY” block letters, and in their first month of in-store testing, sales jumped 22%—no lie. The big mistake here? Treating packaging like a billboard for your website instead of a “first 2-second pitch” to a shopper. Another angle: color contrast. If your card’s background is pale yellow and your text is beige, that’s not “aesthetic”—that’s invisible. We tested this for a skincare client last quarter; their original design had that combo, and when the store’s lighting made the text fade, only 1 in 8 shoppers could read their product claims from 3 feet away. Easy fix: use the Web Content Accessibility Guidelines’ contrast checker, it’s free, and it takes 2 minutes. Stop guessing, use the tool.
Second mistake: overloading the card with info like you’re cramming for a final exam. I get it—you spent time making your product, you’ve got a million selling points, you wanna tell everyone everything. But a card isn’t a user manual. Let’s be real: a shopper isn’t gonna read 15 lines of bullet points about “100% recycled cardboard” plus “non-toxic ink” plus “compostable” plus “made in USA” plus how to use the product, all in one glance. Last year I worked with a portable charger brand that had 18 separate pieces of tiny text on their blister card. We pointed out that even when they trimmed down to the 3 most important points (battery life, compatibility, “no overheating”), their card felt less cluttered and way more intentional. They cut the fluff, and they actually started getting questions from shoppers about the extra stuff that wasn’t on the card, which means they were curious enough to ask instead of scrolling past. The other part of this? Forgetting white space is your friend. If your card feels like it’s bursting at the seams, no one’s gonna stop to look at the product itself, which is the whole point. I once had a candle brand send a design that had a photo of their candle, 6 lines of text, and even a tiny image of the candle’s scent note—all crammed into the front. We suggested moving the scent note to the back, and adding an inch of empty space at the top, and suddenly the card looked like a premium product, not something someone printed at home. It sounds counterintuitive, but less is more.
Third: ignoring the product’s fit like you’re buying jeans one size too small. This is such a basic mistake, but it happens all the time. As a packaging card supplier, I’ve seen brands design the card first, then hunt for a blister or insert that fits, or vice versa, and it shows. For example, a phone grip brand came to us last year with a card that was 2 inches wider than their phone grip, so they had to add extra bubble wrap to keep it from sliding around inside the blister. That extra packaging added cost, and when it got to the store, the blister kept fogging up because there was too much empty space, making the product look used. The fix? Start with the product dimensions before you even open Photoshop. If your product is 3 inches wide, don’t make a 5-inch card just because you want to fit your logo somewhere. We actually have a little checklist for new clients: measure length, width, depth of the product, leave ¼ inch of space on each side for blister tabs, and build the card around that. Another part of this: for things like hang tabs or die cuts, don’t cut a hole that’s too small for a retail hook, or too big that the product wiggles. I once saw a lip balm card that had a hang tab hole so big the lip balm would slide right out during shipping—they lost 10% of their stock before it even hit shelves. Duh. That’s not “quirky design,” that’s a costly error.
Fourth: generic, boring visuals that make your product blend into the shelf. Look around the next time you’re in a store—how many card packages have that same boring stock photo of a product, or the same overused “organic” green leaf graphic? As a packaging card supplier, we’ve seen clients spend hundreds on graphic design that looks like every other product in their category. The candle brand I mentioned earlier? Their original design had that generic green leaf and a stock photo of a candle on a wooden table, which got lost next to 10 other candle brands. We suggested using a photo of their actual candle on their actual windowsill (not a stock image) and a small, unique graphic of their signature scent—like a tiny coffee bean for their vanilla latte candle. Suddenly, their card stood out. Another example: a tech accessory brand selling phone cases that used the same “sleek metallic” graphic as every other case brand, so their cases got passed over. They switched to a photo of their case on a person’s hiking boot, targeted to outdoor folks, and sales doubled in 2 months. The big mistake here? Using generic assets that don’t connect with your target shopper. Stop using stock photos that could be for 100 different products—use visuals that tell a story, even a tiny one on a card. Also, consistency across your brand: if your Instagram uses playful, bright colors, don’t make your packaging card matte black and boring. It’s a disconnect that makes shoppers think you’re a totally different brand.
Fifth: skipping functional stuff because it’s not “pretty.” This is the mistake that kills me, because it’s so avoidable. Functional design isn’t about being flashy—it’s about making sure your product gets to the store intact, and shoppers can actually open it (wait, no, also, some packaging needs to be child-safe, but let’s be real, most shoppers hate packaging that’s impossible to open—don’t make that mistake too). Last quarter, a snack brand selling individually wrapped rice cakes came to us with a card that had a blister sealed so tight, even my team with sharp office scissors couldn’t get it open without ripping the rice cake. We redesigned the seal to have a small tear notch on the top, and suddenly shoppers were leaving reviews saying they could finally open it without wasting the product. Another functional fail: not considering shipping. If your card is going to be shipped in big bulk, don’t make it too thin—we once had a client use 12pt cardstock (that’s pretty thin) and half their boxes arrived with crumpled cards. Switching to 16pt cardstock fixed that. Also, for brands selling fragile products (like small glass decor), adding a small die-cut indent in the card to cradle the product instead of just letting it sit in the blister cuts down on breakage by up to 30%. I know “functional” isn’t as fun as “cool design,” but if shoppers can’t open your package, or your product breaks, they’re not buying from you again.
Wait, and let’s be honest—there’s also that mistake of forgetting the back of the card. So many brands only design the front, like the back is just an afterthought for a barcode. The back is prime real estate! That’s where you can put your Instagram handle, a 1-sentence product story (“Hand-poured in our small Ohio studio”), or a call to action like “Tag us in your candle pics!” The skincare client I worked with last year had their back of the card blank except for a barcode, so we suggested adding their customer review quote (“My acne cleared up in 2 weeks”) and a link to their website. That small addition boosted their website traffic from the packaging by 15%, because shoppers actually looked at the back. Don’t waste that space.
Now, I know a lot of brands get stuck thinking “packaging is just wrapping, it’s not that important,” but here’s the thing: 70% of in-store purchases are impulse buys, according to the Point of Purchase Advertising International. That means your card packaging is the only sales rep your product has in that 2 seconds a shopper is walking by. So fixing these mistakes isn’t just “making it look better”—it’s actually getting people to buy your stuff.
If you’re currently working on a packaging card design, or you’re redoing an old one and you’re not sure if it’s hitting the mark, don’t guess. I’ve helped dozens of brands fix these exact issues, from tweaking text size to adjusting product fit to making sure the back of the card doesn’t go to waste. Hit me up to chat through your needs, no pressure, no awkward sales pitches—just honest feedback from someone who’s seen every mistake in the book.
