Range Architecture

Range architecture is the structural plan for a collection. It determines how many SKUs sit at each price point, what proportion of the range is entry-level volume versus hero-piece editorial, and how categories are balanced against each other. Most designers learn range architecture on the job, usually by watching a range fail in a wholesale review and working backwards to understand why. The discipline exists because a buyer does not purchase individual pieces: they purchase a range. A range that is structurally incoherent (too many heroes, missing basics, unbalanced categories) will fail a buyer review regardless of how good any individual piece is.

No single category should exceed 35% of a range unless the brand is a category specialist. For a womenswear brand, a healthy AW range might be: Outerwear 20%, Knitwear 25%, Dresses 20%, Trousers 15%, Tops 20%. The specific percentages vary by brand positioning and season, but the principle holds: a range heavy in one category signals to a buyer that the designer has a favourite, not a strategy. Category balance also affects the range's commercial surface area: a balanced range has more entry points for the buyer to place into. Run your range through Range Health to see your current distribution before a wholesale appointment.

A well-structured range has three price tiers within it: entry, mid, and hero. Entry pieces represent 20-25% of the range and sit at the brand's lowest accessible price point: this is where new customers come in and where volume is generated. Mid-range pieces represent 50-55% of the range and are the commercial engine: these are the styles a buyer expects to repeat. Hero pieces represent 20-25% of the range and sit at the highest price point: they create the editorial story but are not expected to generate volume. The mistake is building a range that is all hero: aesthetically coherent but commercially unworkable. A buyer cannot build a floor around hero pieces.

Every style needs a minimum of two colourways to be commercially viable in wholesale: buyers need to split between colours across their size buy. Volume styles (mid-range pieces expected to generate repeat orders) should carry 3-4 colourways. Hero pieces can carry 1-2. The colourway strategy should be coherent across the range: a neutral, a fashion colour, and a seasonal accent is a workable three-colourway structure. Avoid introducing a colour in a single style: if a colour appears once in the range, it reads as an afterthought rather than a considered part of the palette.

The five structural failures that kill ranges in wholesale reviews: (1) Hero-heavy ranges, too many statement pieces, not enough volume. (2) Missing basics, no entry-level pieces for the buyer to anchor the range. (3) Single-category dominance, over-relying on one category the designer is confident in. (4) Price gap, a jump from entry to hero with nothing in between. (5) Colour isolation, colours that appear in only one style and cannot be used to build a coherent floor. Each of these is detectable before a wholesale appointment if you run a range health check.

Start with structure, not design. Define your three price tiers first. Then set your category targets (what percentage of the range sits in each category). Then identify your volume styles, the mid-range pieces that will generate repeat orders, and design those before your heroes. Heroes are easier to design than volume pieces, which is why most first ranges get the ratio backwards. Score each concept in Commercial Score before committing to pattern-making. Run the full range through Range Health when you have 8-10 styles drafted. Adjust the structure before cutting any samples. A structurally sound range with imperfect design will outperform a beautifully designed range with structural problems every time.
