5 Best IQ Tests: Find Out Your IQ For Free (And Kids)

There are many different IQ tests available to measure one’s intelligence, but they cost money. Luckily, there are also IQ tests to find out your IQ for free for adults and kids alike. And we have the 5 best IQ tests for you.

Taking a standardized test is the only way of having your intelligence measured. There are different tests suited for people of different ages, including children. Very young children should only take an intelligence test under the supervision of an educational psychologist. There are plenty of different tests available, many of them online but you have to choose your test carefully if you want to get accurate results.

And then, there is the issue of costs. Not all tests available online are free and even if you choose to pay for a test, it does not necessarily mean that the results you get would be accurate.

If you are looking for a test that is both free of cost and accurate, you have come to the right place. In this article, we will tell you what the best IQ tests available for free online are. We suggest you go over the list of 5 tests before choosing which one to take. Of course, as every single one of the tests that we will talk about is free, you can take more than one of them or, even, all of them. Nothing is stopping you so knock yourself out!

Before you start, you need to know that the different tests are presented in no particular order. You are recommended to read our reviews before deciding which one you would like to take.

This intelligence test is purely based on pattern recognition, which makes it ideal for people of all kinds of cultural backgrounds and different ages.

The IQTest.com is only suitable for people who are fluent in English as it is more culturally-specific than some of the other free online intelligence tests that we have reviewed in this article.

That does not mean that all the questions are language-based, far from it. You will need, however, an excellent command of English to answer many of the questions that make out this test.

Having said that, the time you spend on the test will also impact your results, so you should attempt to finish it as quickly as possible.
