Babies grow at an incredible rate in the first weeks and months. In fact, at just 5 months old, your baby will have doubled their weight at birth and tripled it by 12 months.

That’s a crazy rapid growth rate when you stop to think about it. However, not all babies follow this pattern and may need closer monitoring due to premature birth or other issues.

This is when you’ll want to find the best baby scale that will give you precise, fast, and easy to capture measurements.

Too busy loving your little one? Here’s our top pick.

The right baby scale for you will depend on how you want to use it. Our pick for the best baby scale is the Health-o-Meter Grow with Me infant to toddler scale. This multi-function scale allows you to weigh your baby or toddler with consistent accuracy to the nearest ½ an ounce.

Why might I need to weigh my baby at home?

While many parents may not need to weigh your baby at home, it can be exciting to have a record of the baby’s growth. They’ll be measured during their routine well-baby visits, which can provide snapshots of their weight gain.

However, for breastfeeding mothers, it can often be hard to know how many ounces your baby is drinking. Weighing your baby before and after feeding can let you know approximately how much breast milk your infant consumed.

If they aren’t consuming enough milk or formula, it could be time to consult with your pediatrician or a lactation consultant to see how to improve milk intake.

Another reason could be for babies that are born prematurely. They are at higher risk of complications and health issues since their systems may not be fully developed. More frequently weighing a baby on a scale allows parents and pediatricians to ensure they’re developing at a good pace.

It’s also just fun seeing how much your baby is growing each day. When you’re staring at their adorable face all day, it’s hard to see how much they really change day-to-day or week-to-week.

How to Weigh Baby at Home

First and foremost, make sure your scale and baby are on a safe surface. Babies roll and move around a bunch, so there is a potential for them to fall off the scale and get hurt.

The steps to weigh your baby will depend on the type of scale being used. However, is generally how to weigh your little one.

  1. Place the scale on a hard surface since the carpet may reduce accuracy.
  2. Remove all clothes since that can add weight and result in an inaccurate reading.
  3. Get your baby into a completely dry diaper so you’re not measuring water/pee weight.
  4. Place a dry diaper on the scale.
  5. Push the tare button (some may say “zero”) and wait for the scale to read zero.
  6. Remove the diaper from the scale.
  7. Place your baby gently onto the scale.
  8. Wait for your little one to stop kicking and moving since this makes the scale jump.
  9. If they don’t settle (many won’t), push the Hold button to get an average weight.
  10. Finally, record your baby’s weight on their chart.

Can you weigh a baby on a regular scale?

While you technically could use a regular scale, it’s not recommended due to the high likelihood of inaccurate measurement. You can get a general weight by holding your baby while you step in the scale and subtracting your own weight.

However, you won’t be able to get an accurate reading since these scales might only go the nearest tenth of a pound. Not to mention, you’re likely holding a squirming baby.

Different Types of Baby Scales


With the highest level of accuracy, a digital baby scale is easy to use and typically able to measure down to the closest half-ounce or better. Since they are digital, many scales can also convert your baby’s weight between ounces, pounds, and kilograms in real-time. They present the final result on an LCD screen in big numbers so it’s easy to read while your little one is moving around.


This is the type of scale your pediatrician will likely use to measure your baby’s weight during doctor’s visits. The mechanical baby scales have little sliders that you manually balance out in order to tell you how many pounds and ounces your baby weighs.


The hanging scale is maybe the lesser-used device for baby weigh-ins. More commonly, these baby scales are used for measuring fish and animals since there isn’t a good way to keep them still. They work by placing the baby in a cloth sling and lifting them up by a hook on the scales to get a reading.

Bath Tub

The bathtub scale is an innovative way to weigh your baby while they are already undressed for bath time anyway. These tubs can weigh your little one with or without water thanks to its zero function which subtracts the water weight.

Changing Pad

You’re likely changing baby diapers 8-10 times a day at first. With a changing pad scale, you can quickly record their weight during one of those diaper changes.


If you’re constantly on the go with your baby, a portable scale may be just what you need. They’re often smaller in size to fit in a bag that can be carried with you anywhere.


Besides calculating your baby’s weight, some baby scales are capable of measuring their height or length and may come with measuring tape to get their head circumference. This often involves a spot to place their head and an extending leg piece with a ruler to capture their length.

These multipurpose baby scales often have pieces that you can remove to allow for the weighing of toddlers and older kids. It can even be used for cats, dogs, and other pets (when no longer needed for your baby).

How often should I weigh my baby?

This depends on exactly why you’re weighing your baby or toddler. In general, tracking an infant’s weight over time is a good way to assess their overall health and growth.

Unless there are health concerns like low birth weight, it’s typically sufficient to weigh your infant every few days and chart their growth to make sure everything is on track. There are some changing pad scales that help make it part of everyday life.

However, it’s especially important during the first few days and weeks after birth to monitor your newborn’s weight gain. This allows you to check if they’re growing at a normal rate and can help identify early signs if there may be any health concerns.

As a word of warning, having a scale at home can make some anxious mommies even more worried than they should be. Stay calm if your baby seems to be under or overweight until you can discuss it with your pediatrician. The range for “normal” is much larger than it seems on paper.

What is a baby growth chart and what should I be measuring?

Your pediatrician will capture three particular measurements during each of your infant’s wellness visits. The chart will help to set a baseline and keep track of your baby’s growth over time.

The 3 main measurements on the growth chart are: 

  • Body Weight
  • Head Circumference
  • Height or Length

A baby’s growth is measured based on the World Health Organization (WHO) charts for baby boys and girls under the age of two. However, just because your child is in a higher or lower percentile on the chart doesn’t necessarily mean it’s anything bad.

Below is what the rather complicated chart looks like. However, there are many apps that simplify this charting for you and some even sync with scales to automatically populate the data.

World Health Organization (WHO) Child Growth Charts

The pediatrician will be looking at many factors and data points to determine any health concerns. After all, each one of us begins this journey through life at a different starting point.

What features should I consider on a baby scale?

Accurate Reading: The level of accuracy is important since you don’t want readings all over the chart at each weighing. Word of Caution: Unless you want to pick up an expensive scale like they have the doctor’s office, you can’t expect 100% accuracy since your baby will be moving around.

High Precision: This is most critical if you’re trying to understand how much milk the baby has consumed while breastfeeding. Some scales will be able to provide an accurate weight with great precision, sometimes down to just 0.1 ounces.

Easy to Read Screen: Babies wiggle and squirm a lot, I mean, A LOT. A bright and large digital LCD screen makes it easy to read their weight with a quick glance.

Quick Measurement: As mentioned above, they don’t like to stay still and even less so when they don’t have clothes on. You also don’t want a potty accident during the weighing, so the measurement should be done in seconds.

Hold Feature or Function: To make things easier and more accurate, most baby scales have a hold button that pauses the scale. Some also use this to average out numbers since it will jump up and down as the baby moves around.

Tare Function: If you don’t want to remove your baby’s diaper, most scales allow you to enter a tare or subtract that weight from the total. This is as simple as placing an unused diaper on the scale and pushing the tare or zero buttons before putting the baby on the scale.

Non-Slip Pad: Scales with slip-resistant padding provide you additional support as you wrestle to keep your baby on the scale. The extra grip prevents them from slipping and sliding on the smooth plastic.

Curved Tray or Pad: In addition to the padding, a curved baby tray is another safety feature that will cradle your baby to help keep them on the scale during weigh-ins.

Weight Limit: This will depend on how long you expect to use the scale. Some are made specifically for infants, while others have a higher weight capacity and can be used for toddlers or bigger kids.

Built-in Changing Pad:  A combination of a digital baby scale and changing pad are ideal to weigh your baby during this activity you do (many times) every day. These have softer padding and curved sides to keep your baby comfortable and safe.

Weight & Portability: The scale’s weight and size may be important if you’re always on the go or maybe just want to tuck the scale away when not in use. Some are able to come apart in several pieces to make them easy to move.

Battery Powered or Plug-in: Digital baby systems will require a source of power for the LCD screen and other scale functions. Most will use 2 to 3 AAA or AA batteries, but a plug-in scale will limit where you can place it.

How much should my baby weigh?

This will vary greatly based on your particular situation since the baby’s starting weight will depend on how early or late they arrived. Pre-term babies will generally be below the average baby weight while late-term babies will be larger.

Their target weight will also depend on their length or height since longer babies are naturally heavier than short babies. The WHO growth chart percentile ranges are based on weight-for-length.

We recommend using a chart to consistently keep track of the baby’s growth and discuss the results with your little one’s pediatrician.
