The difference between a trading card that feels like a proper collectible and one that feels like a flimsy printout comes down to card stock. This guide explains GSM weights, paper finishes, and why CardStar uses 350gsm premium stock for every card we print.
GSM stands for grams per square metre — it's the standard measure of paper and card weight. Higher GSM means thicker, more rigid material. Standard printer paper is around 80gsm. Business cards typically range from 300–400gsm. Premium trading cards sit in the 300–350gsm range.
When you hold a card, GSM is what determines whether it feels substantial or cheap. A 200gsm card bends easily and feels like photo paper. A 350gsm card has satisfying rigidity — the kind you'd want to sleeve and display.
Every CardStar card is printed on 350gsm premium card stock — the same weight used by Topps, Panini, and Upper Deck for their standard trading cards. This weight strikes the ideal balance: sturdy enough to feel collectible, flexible enough to slide into sleeves without damage.
We don't offer lower-weight options because they don't meet our quality bar. If you're creating a card for a birthday, end-of-season presentation, or personal collection, it should feel like the real thing.
Card finish affects both appearance and durability. Glossy finishes reflect light, making colours pop and giving cards that classic trading card sheen. They're more prone to fingerprints but easier to clean. Matte finishes reduce glare, feel softer in hand, and resist fingerprints better.
CardStar uses a semi-gloss finish that balances vibrant colour reproduction with practical handling. It photographs well, displays nicely, and doesn't show every touch.
Coated card stock has a thin layer applied to the surface, improving print quality and protecting against minor scuffs. Uncoated stock absorbs ink differently, creating a softer look but offering less protection.
All CardStar cards use coated stock for sharp image reproduction and improved durability. The coating also makes cards more resistant to humidity and handling wear.
Online photo printing services often use 200–250gsm photo paper. While images may look acceptable, the card feels wrong immediately. It bends too easily, doesn't sit flat, and won't survive being handled or displayed.
Proper trading card stock costs more to source and print, which is why cheap alternatives exist. But when you're creating something meant to last — a gift, an award, a keepsake — card quality matters more than saving a quid.
What GSM are CardStar cards?
All CardStar cards are printed on 350gsm premium card stock — the same weight as official trading cards from Panini and Topps.
Are CardStar cards glossy or matte?
We use a semi-gloss finish that offers vibrant colours and that classic trading card sheen while remaining practical for handling and display.
Will my card feel like a real trading card?
Yes — our 350gsm coated card stock matches the weight and feel of professional trading cards. It's rigid, durable, and fits standard sleeves.
Can I choose a different card stock weight?
We only offer 350gsm because it's the quality standard for trading cards. Lower weights don't meet our bar for a proper collectible.
How durable are the cards?
Very durable with normal handling. The coated finish protects against minor scuffs and humidity. For long-term preservation, we recommend penny sleeves or top loaders.
