Question 1

Dale-Chall Words List

Accepted Answer

The Dale-Chall readability formula developed by Edgar Dale and Jeanne Chall is calculated by counting difficult words in a piece of text, where those words are simply those not found on a list of common words - much like the Spache Readability Formula.

Those common words are a list of words with which 80% or more of fourth-grade students are familiar.

That word list has been modified over time, and the current version of the formula - the New Dale-Chall Readability Formula - uses about 3,000 words in its list. For your reference, here they are! Texts written using just these words are likely to be easy to read for fourth-grade students and higher.

Question 2

What is the Spache Words List?

Accepted Answer

The Spache readability formula uses a set of familiar words. The text is then scored against this, with unfamiliar words decreasing readability.

Spache scores are most useful for children up to grade four. Above this, the New Dale Chall formula is best for older children.

The Spache word list is as follows:

a
able
about
above

act

Question 3

What's a good readability score?

Accepted Answer

We always recommend aiming for a Readable grade A. This ensures that your writing will reach the general public.

If you're measuring your text with the Flesch Kincaid Grade Level, we recommend aiming for a FK Grade 8. This corresponds to 8th Grade in the USA education system. It is recommended for the general public.

It doesn't mean you're writing for an eighth-grader. Certainly, an eighth-grader can understand your content if it's written to that level. But writers and marketers from a wide variety of fields can benefit from this. Adults enjoy reading several grades below their actual reading level. Further, a lower Flesch-Kincaid Grade Level makes your content skimmable. This saves your reader's time. It also saves your time by reducing queries.

Question 5

What are Lazy Words?

Accepted Answer

Lazy Words is a list of words exclusive to Readable. Our tool will highlight words people commonly fall back on.

For example, instead of "they ran very fast", you could say, "they sprinted". This is both simpler and more evocative.

Question 6

What is the Flesch-Kincaid Grade Level?

Accepted Answer

The Flesch Kincaid Grade Level is a widely used readability formula. It assesses the approximate reading grade level of a text.

The Flesch-Kincaid Grade Level is equivalent to the US grade level of education. It shows the required education to be able to understand a text.

The formula is as follows:
