Designed by Cardioid

Cardioid Cards is an independent Australian stationery brand and curated paper goods store focused on meaningful, design-led connection. Alongside its in-house Cardioid collection — minimalist greeting cards featuring concise three-word statements and understated typography — Cardioid Cards also showcases thoughtfully selected stationery, greeting cards, and art prints from independent artists and studios around the world.

Designed to communicate encouragement, love, support, and everyday sentiment through simple, intentional design, the Cardioid collection reflects the brand’s belief in thoughtful communication and lasting connection.

The name “Cardioid” derives from the Greek word kardia, meaning heart. In mathematics, a cardioid is a heart-shaped curve — a subtle reference to the emotional intention behind each card. Designed in Canberra and foil-printed in New Zealand on premium 540gsm cardstock, Cardioid Cards combine contemporary minimalist aesthetics with high-quality craftsmanship.

Created as keepsakes rather than disposable greeting cards, each single-sided card is paired with a grey envelope and designed to be displayed on a wall, desk, fridge, or pinboard as a quiet daily reminder. The collection reflects a modern approach to greeting cards and paper goods — thoughtful, design-led, and made for meaningful everyday moments.
