Market Sizing

Bottom-up and top-down estimates of market value, volume and growth, with assumptions and sources shown in full.

Overview

We size markets using triangulated bottom-up and top-down methods, drawing on trade, customs, procurement and company-level data alongside primary interviews with buyers and suppliers. Every estimate is delivered with a documented data appendix, explicit assumptions and sensitivity ranges, so a client and its stakeholders can interrogate the numbers rather than take them on trust. Studies typically size a market by value and volume, split by segment, geography and channel, and project a five-year outlook under base, upside and downside scenarios.

Methods

How the work is done.

The methods below are documented in every market sizing engagement, so the findings can be checked and reproduced.

  1. Bottom-up estimation from unit volumes, pricing and penetration data

  2. Top-down triangulation using trade, customs and national accounts data

  3. Structured interviews with buyers, suppliers and distributors

  4. Scenario modelling with documented assumptions and sensitivity ranges

  5. Independent review of methodology and data sources before publication

Example outputs

What you receive.

Deliverables are agreed at scoping. A typical engagement produces:

  • Sized market model (value and volume) by segment, geography and channel
  • Five-year base, upside and downside forecasts
  • Data appendix listing sources, assumptions and confidence ranges
  • Executive summary deck suitable for board or investor circulation
Relevant sectors

Where this work is commissioned.

Market Sizing is most often commissioned across these sectors, though the method travels well beyond them.

  • Financial services
  • Health & life sciences
  • Technology & telecommunications
  • Energy & natural resources
  • Consumer & retail
Common questions

Frequently asked.

How do you handle markets with limited public data?

Where published data is sparse, we combine proxy indicators — trade flows, procurement records, patent filings — with structured expert interviews, and we state the resulting confidence range explicitly rather than presenting a single unsourced figure.

Can the model be updated after delivery?

Yes. Models are delivered with assumptions and formulas documented so a client's own team can update inputs, and we offer fixed-scope refresh engagements on request.

How long does a market-sizing study typically take?

Most engagements run six to ten weeks from scoping to final report, depending on the number of segments and geographies and the availability of primary data.
