When B2B buyers search for dried flowers with specific "card size" attributes, they're typically referring to one of three distinct specifications that directly impact pricing, packaging, and end-use applications. Understanding these distinctions is essential for suppliers looking to sell on Alibaba.com effectively and match buyer expectations.
Flower Head Diameter Specifications represent the most common interpretation of size grading in the dried flowers industry. According to industry standards from Kunming source factories, preserved roses are classified into six standardized sizes: 2-3cm, 3-4cm, 4-5cm, 5-6cm, 7-8cm, and the luxury 9-10cm heads [2]. Each size category serves different market segments—smaller sizes (2-4cm) are popular for potpourri, resin crafts, and decorative fillers, while larger heads (7-10cm) command premium pricing for wedding arrangements and high-end interior design.
Packaging Card Dimensions refer to the physical size of product cards, hang tags, or specification sheets that accompany wholesale shipments. For bulk orders, medium to large sizes (10"x13" and above) are standard for wholesale bundles, event decor, and commercial florists needing bulk inventory [3]. These dimensions ensure flowers remain protected during transit while providing adequate surface area for care instructions, origin information, and handling guidelines.
Sample Card Formats are critical for B2B transactions where buyers need to evaluate quality before committing to large orders. Sample cards typically display multiple size grades side-by-side, allowing buyers to compare color retention, petal integrity, and stem length across different specifications. Suppliers who provide detailed sample cards with clear size labeling report higher conversion rates on Alibaba.com because buyers can make informed decisions without physical inspection.
"Request detailed size specifications (e.g., petal length, bloom diameter, stem length). Ask suppliers if flowers are sorted by size before packaging—this affects consistency and pricing." [3]
