Weight-only or smart scale?

A weight-only digital scale measures one thing well: your weight. Smart scales add an app and often body composition estimates using a small electrical current. If you only need weight, a basic scale is simpler and avoids the app and data sharing. If you want body fat and muscle estimates, read our body composition scale guide first, because those readings vary much more than weight.

Two weight-only scales compared

All figures are from Etekcity's published specifications. Both list a 2-year limited warranty.

Specs that matter

• Capacity. Choose a capacity comfortably above your weight. The Etekcity examples list 400 lb and 440 lb; heavy-duty scales with higher limits are also sold.
• Increments. This is the smallest step the display shows. Both Etekcity examples show 0.2 lb or 0.1 kg steps. A finer increment is not the same as better accuracy; it only changes what the screen shows.
• Platform size. A wider platform is easier to stand on steadily. Compare the listed dimensions to your foot size.
• Units. Both examples switch between lb and kg.
• Batteries. Check the type and count. The examples use AAA cells.
• Display. A large, high-contrast screen is easier to read, especially without glasses.

How to weigh consistently

• Put the scale on a hard, flat floor.
• Weigh at the same time of day under similar conditions.
• Stand still in the center with weight spread evenly on both feet.
• Look at weekly trends rather than day-to-day changes.

A tempered glass platform can be slippery when wet. Step on with dry feet and hold onto something if your balance is unsteady.

Does weighing yourself help?

In a 6-month randomized trial of 54 men with overweight or obesity, the group that self-weighed, along with individualized motivating content, lost more weight than a group without self-monitoring. Both groups received the same nutrition advice. The authors concluded that self-weighing can help people lose additional weight.

Some people worry that frequent weighing hurts mood. A meta-analysis of 29 tests found no association between self-weighing and affect, body-related attitudes or disordered eating, but a small negative association with psychological functioning such as self-esteem. If weighing makes you anxious or triggers unhealthy eating, weigh less often and talk with a health professional.

Weighing over the long term

Self-weighing may help keep weight off, too. A three-year follow-up of a self-weighing trial contacted participants after the study ended. Of 98 people in the original trial, 36 took part in the follow-up. Their average weight loss during the trial was 12.7 lbs, and over 75% of them were still weighing themselves at least once a week. The authors suggested frequent self-weighing may be an effective, low-cost strategy for weight loss maintenance, while noting that more research is needed on long-term weight gain prevention.

Because only 37% of the original group took part, the follow-up cannot show that weighing caused the result. Still, a simple, reliable scale is the tool that makes regular weighing easy.

Care and safety

• Replace batteries when the display dims or shows a low-battery sign.
• Wipe the glass with a damp cloth; avoid soaking the scale.
• Do not jump onto the scale or use it as a step.
• Stay under the maximum capacity.

If you are tracking weight for a medical reason, follow your doctor's instructions on how and when to weigh.

What to look for when you buy

Questions people ask

Are digital bathroom scales accurate?

Makers describe their scales as accurate, but the increment shown is not the same as accuracy. Use one scale on a hard floor and compare trends.

What capacity do I need?

Comfortably above your weight. Etekcity's examples list 400 lb and 440 lb.

Should I weigh myself every day?

Pick a routine you can keep and watch trends. Weigh less often if it affects your mood.

Why does my weight change during the day?

Food, fluids and clothing change body weight through the day. Weigh at the same time under similar conditions.

Do I need a smart scale?

Only if you want app tracking or body composition estimates. Weight-only scales are simpler.
