In a Common size statement each item is expressed as a percentage of some Common base.

Common Size Statement, also known as component percentage statement, is a financial tool for studying the key changes and trends in the financial position and operational result of a company. Here, each item in the statement is stated as a percentage of the aggregate, or revenue from operations of which that item is a part. For example, a common size balance sheet shows the percentage of each asset to the total assets, and that of each liability to the total liabilities. Similarly, in the common size statement of profit and loss, the items of expenditure are shown as a percentage of the revenue from operations. If such a statement is prepared for successive periods, it shows the changes of the respective percentages over a period of time.
