What is Product Range?

Product Range

Product Range is the full set of products a company offers, taken together and considered as a portfolio. Range is characterised on two axes: width (how many distinct product lines) and depth (how many variants within each line). A hardware retailer might carry 12 lines (width) with 8 screen sizes each (depth). The strategic question is rarely “how many products?” but rather “which shape of range serves our target audience best while remaining operationally coherent?”

Width versus depth

Broad range, shallow depth. Many distinct lines with few variants each. Convenience stores, general-purpose SaaS suites, department stores. The proposition is “we have everything you might need”; the operational cost is managing many vendors and thin expertise per category.

Narrow range, deep depth. Few lines with many variants. Specialty retailers, category-defining SaaS tools. The proposition is “we know this one thing exceptionally well”; the operational advantage is expertise concentration and brand clarity.

Broad and deep. The ambitious shape. Amazon’s product range. Microsoft’s software portfolio. Requires massive scale to sustain and is mostly unreachable for anyone below scaled-incumbent size.

Narrow and shallow. Often the starting position. A single product in a single variant. The constraint is capacity or focus, not strategy. Most startups live here.

The expansion trap

Product range tends to expand over time because individual line extensions each look like a good idea in isolation. A new colour, a new size, a new bundle, a new tier. Each extension has its own advocate (a PM, a sales rep, a customer) and its own local business case. Range growth is the compound outcome of many small yes decisions.

The trap is that range-complexity cost compounds faster than range revenue. Specifically:

Operational overhead. Each SKU needs forecasting, stocking, support, documentation, maintenance. Overhead grows roughly linearly with SKU count; revenue often does not.

Customer decision cost. Too many options increases abandonment. The Iyengar-Lepper jam study showed 30% conversion on 6 options versus 3% on 24. Real buying behaviour doesn’t scale linearly with choice.

Brand dilution. A clear position requires clear product coverage. A range that sprawls across positioning dimensions makes the brand harder to understand.

Internal cannibalisation. New variants often steal sales from existing ones more than they capture net-new buyers. The line count grows; total revenue doesn’t.

Pruning discipline

The complement to expansion is deliberate pruning. Three useful tests:

The 80/20 check. Sort SKUs by revenue. The bottom 20% of SKUs typically generate under 3% of revenue while consuming a disproportionate share of operational attention. These are pruning candidates unless they serve a specific strategic role (loss leader, gateway, demo).

The strategic coherence check. For each product, answer: which customer is this for, and how does it reinforce our positioning? If the answer is vague, the product is drifting outside the range’s strategic shape.

The discontinuation-regret check. Imagine the product didn’t exist. Would you launch it today, knowing what you now know about the cost structure? If not, that’s a pruning signal, not a protection argument.

An example

A consumer electronics brand inherited a range of 340 SKUs across 18 product lines after a decade of acquisition-driven expansion. A range audit grouped SKUs by contribution margin and strategic fit. The bottom third - 110 SKUs - generated 4% of revenue and absorbed an estimated 22% of support and warehousing costs. Pruning them took 18 months and was politically painful (each SKU had a sponsor), but the resulting range was clearer for customers, cheaper to operate, and led to a 12% gross margin improvement within two years. Range discipline was the mechanism; the strategy was focus.
