Bag shoppers navigate by what fits: phone, phone-plus-water-bottle, laptop, overnight. A size chart organized around carried objects — not designer vocabulary — is what turns a bag wall from a pile into a shelf, and it is the spec table wholesale listings almost never publish.
The six-size working chart
| Size class | Interior (approx) | Fits | Retail band |
|---|---|---|---|
| Phone mini | 19×11 cm | Phone, cards, lipstick | $22-38 |
| Small crossbody | 22×16 cm | Phone, wallet, sunglasses | $32-52 |
| Medium shoulder | 28×22 cm | Plus tablet, small umbrella | $42-68 |
| Day tote | 34×28 cm | Plus laptop 13 in, lunch | $48-85 |
| Structured weekender | 45×30 cm | Overnight kit | $65-120 |
| Foldable beach/shopper | 40×35 (collapses) | Towel, market haul | $24-45 |
Strap drop matters as much as interior: 50-60 cm crosses the body, 25-30 cm shoulders, under 20 cm hands or crooks of the arm. The phone-mini tier's spec discipline is detailed in the three-material phone shelf guide.
Which sizes carry a boutique's bag wall?
Four of the six: phone mini (impulse), small crossbody (volume), day tote (margin), foldable shopper (seasonal attach). Medium shoulder and weekender are depth buys — add them when sales data shows commuters or overnight travelers in your clientele, not before. The structured-tote construction specs are in the handwoven tote guide.
Why do interior dimensions beat silhouette names?
"Mini," "medium" and "large" mean nothing across suppliers — one factory's medium is another's mini. Centimeters travel: a buyer comparing three suppliers' small crossbodies needs 22×16 vs 24×18, not adjectives. Listings that publish interiors also earn the "true to size" review line that lifts conversion on the whole shelf.
How do sizes map to materials and seasons?
Phone minis run knit in gift months, suede in fall, straw in resort — the rotation from the phone shelf calendar. Day totes run handwoven spring-fall and mesh in summer, per the foldable beach bag guide. Weekenders are fall-winter fabric stories. Size class sets the slot; material sets the season.
What is the size-balanced opening order?
24 bags: 8 phone mini, 8 small crossbody, 6 day tote, 2 foldable shopper tests. Roughly $250-400 wholesale. Keep weekenders and medium shoulders out of order one — they consume carton volume disproportionate to their first-month velocity, and volume is what consolidated DDP freight charges you for.
Valvive's catalog spans the chart from knitted phone minis to the structured handwoven day tote, all from 3 pieces per style in one mixed DDP order. Request a quote; pricing returns in 1-2 business days.
