Less vs Fewer: Difference, Rules & Examples

Use fewer when comparing the number of individual things and less when comparing an amount or degree.

Compare:

The revised timetable includes fewer evening services.

The revised timetable leaves passengers with less time to make their connections.

Services are separate events you can count. Time is treated as an amount.

This is the usual distinction in standard English, but expressions involving measurements, percentages, and certain numbers do not always follow it in the way you might expect.

Less vs Fewer: The Main Difference

Fewer is the comparative form of few, while less is the comparative form of little.

The important question is how the quantity is expressed in your sentence, not whether the things involved can physically be counted.

Fewer for Countable Nouns, Less for Uncountable Nouns

Use fewer when comparing individual people, objects, events, or other things counted separately.

The updated registration process resulted in fewer incomplete applications.

Use less when the noun refers to an amount, material, or quality rather than separate units.

The gallery’s new lighting system uses less electricity than the previous one.

The difference becomes clearer when you describe the same situation in two ways.

The school now uses fewer printed forms.

The school now uses less paper.

Forms are individual items. Paper refers to the material being used.

Another example is furniture:

The renovated room contains fewer pieces of furniture.

The renovated room contains less furniture.

You can count individual chairs and tables, but furniture itself is normally an uncountable noun. Adding pieces of makes the individual units clear.

Less Of vs Fewer Of

When referring to part of a particular group or amount, use fewer of with plural countable nouns and less of with uncountable nouns.

Fewer of the shortlisted candidates accepted the revised offer.

Less of the allocated funding was needed after the project was redesigned.

The first sentence concerns a number of candidates. The second concerns an amount of funding.

Less With Adjectives and Adverbs

Less can also express a lower degree when modifying adjectives or adverbs.

The revised instructions are less complicated than the original version.

After the maintenance work, the machinery began to fail less frequently.

You cannot replace less with fewer in these sentences. The comparison concerns degree or frequency, not a number of individual things.

Less Than vs Fewer Than

Both expressions are used with comparisons involving numbers. The appropriate choice depends partly on what the number represents and the writing convention being followed.

Fewer Than for Individual Things

In careful edited English, fewer than is usually preferred when counting separate people or objects.

Fewer than twenty residents attended the consultation meeting.

The repair team completed the work with fewer than six replacement parts.

However, less than also has an established use before some numerical expressions involving countable things.

For example:

Less than twenty applicants remained on the waiting list.

This wording is understandable and has a basis in accepted usage, particularly when the number is treated as a threshold.

Nevertheless, fewer than twenty applicants is the safer choice for formal writing that follows the traditional countable-noun rule.

Less Than for Measurements

Less than is standard when comparing amounts of time, money, distance, weight, and similar measurements.

The ferry crossing takes less than forty minutes.

The replacement equipment cost less than £800.

The village is less than five miles from the nearest railway station.

Even though these expressions contain numbers, they describe measured quantities.

Compare:

The revised work schedule includes fewer hours.

The inspection took less than three hours.

The first sentence compares the number of hours included in the schedule. The second describes a period of time.

You do not need to choose fewer simply because a plural unit follows a number.

Less Than or Fewer Than With Percentages?

Percentages are a case where established editorial guidance does not always follow the basic countable-noun rule.

Less than is widely accepted when comparing a percentage with a numerical threshold, even if the percentage refers to people.

Less than 15 percent of employees participated in the optional survey.

Both the MLA Style Center and The Chicago Manual of Style accept less than in percentage expressions of this kind.

Some usage guides prefer fewer than when the emphasis is on a number of individual people or objects represented by the percentage.

For general writing, less than is a natural and widely accepted choice before a percentage. When following a publication’s style guide, use its preferred convention.

Why Do We Say One Less?

You may hear:

The revised timetable has one less evening service.

This is standard English, even though service is countable.

The construction one less + singular countable noun is well established.

Compare:

One less appointment was needed after the initial assessment.

Two fewer appointments were needed after the initial assessment.

The first uses a singular countable noun after one less. The second uses a plural noun after two fewer.

Is “10 Items or Less” Correct?

Supermarket checkout signs often say:

10 items or less

Under the traditional countable-noun rule, the preferred wording would be:

10 items or fewer

Because items is a plural countable noun, fewer is a dependable choice in carefully edited writing.

However, 10 items or less is also an established everyday expression. It is widely understood and has a long history in English usage.

Merriam-Webster recognizes this kind of numerical construction, so it would be misleading to suggest that the expression is simply an invented or meaningless error.

That does not make less and fewer interchangeable in every situation.

For example:

The second draft contained fewer spelling errors.

This remains the more natural choice in careful writing. Less spelling errors occurs informally, but many editors would change it to fewer spelling errors.

For a checkout sign, either wording is understandable. If you prefer to avoid the distinction, another option is:

Maximum 10 items
