With the help of a button, we can get all kinds of information. It is much easier to get a accurate temperature with digital thermometers, which used to take several minutes to get a true reading.

“If you haven’t upgraded your mercury thermometer, now is the time to swap it out for a modern one.”

But with so many types of thermometers on the market, how do you choose the right one? Good question!

We have selected one of every type to highlight key features and things you should consider before choosing yours.

The first thing to consider is how you’re going to use it. Some thermometers are geared toward infants or children, while others are better for adults.

If you prefer oral, ear, forehead, or no contact, you should decide. An ear thermometer is probably not a good choice if you tend to get a lot of earwax. Many thermometers are used multiple times.

You should avoid glass thermometers, which can break, and mercury thermometers, which are dangerous.

When choosing a thermometer, there are other things to consider.


“A Thermometer is used to gauge body temperature. Paying more won’t necessarily buy accuracy. The most accurate thermometers are first rectal and oral. The less sensitive your reading is, the farther you get outside the body.”

Digital is the best option for pacifier and evi strips because they are known to be inaccurate.

Ease of use

Can you get a reading on your temperature in a few minutes? Is it easy to operate or is it difficult to do?

It probably is if it looks too complicated.


Look for things that matter to you.

  • Do you need a large display?
  • Would a flexible tip be better for your kids?
  • Do you want to hear a loud bang or not?
  • Is it useful to have a lot of memory?

Pick one that checks off your must-haves.

If you prefer a different method, make sure your digital thermometer has that option.


You may not need anything fancy with the Thermometers loaded with extras. There are many simple digital thermometers that do the job for under $20

If you want to buy two options, you can pay less than you would for a more expensive model.

You can expect to pay more if you want some of the bonus features. There is a money-back guarantee.


If you are interested in inexpensive models, look at product reviews. If possible, check out more than one site.

Consistency is important because every product will have some negative reviews. It is worth considering if a particular pro or con is pointed out by many reviewers.

We all have our preferences. The best temperature for you is not necessarily the best for someone else. We are paying special attention to this article.

  • Design. We looked for thermometers that don’t complicate things when you’re looking for clarity. It should be intuitive and easy to use.
  • Speed. You or someone you love is sick. You want to know if there’s a fever, and you want to know now so you can take the next steps.
  • Readability. You shouldn’t have to turn on a spotlight or squint hard to read a thermometer.
  • Accuracy. What’s the point if you can’t trust the reading?

The sellers of these products were not given a heads up. They did not ask or pay for the inclusion in this article.

Another thing to remember is that sales for thermometers are booming, in large part due to COVID-19. Some products may be out of stock right now, but hopefully, they’ll be available again soon.

The COVID-19 pandemic is affecting supply and demand. Here is our price guide.

  • $ = under $20
  • $$ = $20–$50
  • $$$ = above $50

Check the prices for current prices.

Our use of the word “best”

All thermometers must pass federal standards.

So really, no thermometer brand should be “more accurate” than another, though a brand may have more or less consumer trust.

But people tend to prefer the features of some thermometers over others. And some types are known to be the most precise in general.
