Frequently Asked Questions
What size poly mailer is cheapest for shipping a hoodie on eBay?
The right poly mailer size for a folded hoodie is a 10x13 — smaller than most resellers assume, which saves \.10–\.30 per label versus default 12x15.5 bags. Hoodies compress flat to around 8x10 inches, so a 10x13 fits comfortably without oversizing. On 50 shipments a week that packaging trim adds up to real margin. Dresses and longer tops may need 12x15.5, but sweatshirts and hoodies rarely do.
How do I choose the right poly mailer size to avoid split seams on eBay orders?
Picking the right poly mailer starts with folding the garment flat and measuring its folded dimensions. Select a bag that adds at least one inch of clearance on each side so the seam does not stress in transit. Thicker items like fleece-lined hoodies and heavy jackets need a 12x15.5 or 14x17 even when folded compact — material springs back under pressure. Lightweight dresses and blouses typically fit a 9x12 or 10x13. Measuring once before you list prevents wasted poly and split-seam returns.
Which poly mailer size covers the most common eBay clothing categories?
Poly mailers in the 10x13 and 12x15.5 sizes cover the majority of eBay clothing categories for resellers. The 10x13 handles folded tees, blouses, leggings, and lightweight tops. The 12x15.5 fits hoodies, jeans, dresses, and mid-weight jackets. A 14x17 handles bulkier coats and doubled-up bundles. Stocking these three sizes eliminates guesswork at pack time and keeps you from overbuying large bags for small items, which adds unnecessary cost to every outbound shipment.
