Withings Body Scan vs Body Comp: Which Smart Scale Wins in 2026?

Withings has quietly built the most credible lineup of connected scales on the market, and at the top of that lineup sit two very different devices. The Body Comp is a feature-rich body composition scale aimed at people who want to understand what their weight is actually made of. The Body Scan is the flagship, a “longevity station” that turns your morning weigh-in into a near-clinical health check. They look similar on a bathroom floor, but the gap between them in capability, and in price, is large.

If you are deciding between the two in 2026, the question is not really which one is better. The Body Scan is clearly the more advanced device. The real question is whether the extra features justify the cost for the way you plan to use a scale. Here is how they stack up.

Price and where they sit in the range

The Body Comp is Withings’ mid-to-upper option and, at the time of writing, lists at around $229.95 on the Withings web store, depending on retailer and color. That price includes a one-month trial of the company’s Withings+ subscription, a two-year warranty and a 30-day money-back guarantee. The Body Scan is the premium tier and lists at around $499.95, and it is frequently bundled with a Withings+ trial as well. Prices drift with sales and retailer, so treat these as ballpark figures rather than fixed numbers.

To complicate the picture, Withings used CES 2026 to announce the Body Scan 2, a longevity-focused successor priced at around $599.95 that tracks more than 60 biomarkers, adds impedance cardiography and introduces a cuff-free hypertension risk notification. It is expected to ship in the US through 2026, with some of its ECG and blood-pressure features arriving only once FDA clearance is granted. If you are eyeing the very top of the range, it is worth checking whether the newer model is available, and cleared, before committing to the original Body Scan.

That roughly $270 gap between the current Body Comp and Body Scan is the crux of the decision. You are paying for two things: a retractable handle and the cardiovascular hardware it enables.

Spec comparison: Body Scan vs Body Comp

What they share

Both scales are built on the same core. Each uses multi-frequency bioelectrical impedance analysis (BIA) to estimate body composition, so both report weight, body fat percentage, muscle mass, bone mass, water percentage, visceral fat, and basal metabolic rate. Both connect over Wi-Fi and Bluetooth, sync automatically to the Withings app, and push data into Apple Health, Google Fit, and popular apps like MyFitnessPal. Both support multiple users in a household and include the thoughtful touches Withings is known for, such as a weight-only “eyes-closed” mode for people who would rather track trends without seeing a daily number, plus pregnancy and athlete modes.

Both also estimate vascular age and offer Withings’ nerve and vascular health assessments, although some of the more advanced readouts are tied to the optional Withings+ subscription. In other words, the Body Comp is already a genuinely sophisticated health scale. If you have read our Withings Body Smart review, think of the Body Comp as the Body Smart with a layer of cardiovascular and metabolic insight added on top. And if you already own a Withings sleep tracker, the scale data slots into the same timeline; our Withings Sleep Analyzer review covers how those pieces work together in the app.

What the Body Scan adds

The Body Scan’s defining feature is the retractable handle that lifts out of the base. When you hold it during a measurement, the scale completes an electrical circuit through your whole body rather than just your legs, and that unlocks two things the Body Comp simply cannot do.

Segmental body composition

With the handle, the Body Scan measures fat and muscle mass across five separate body zones: your torso, both arms, and both legs. A foot-only scale like the Body Comp can give you an excellent whole-body estimate, but it cannot tell you that your left leg is carrying noticeably less muscle than your right, or track how upper-body training is changing your arms over time. For anyone rehabbing an injury, following a structured strength program, or simply curious about muscle balance, segmental data is the headline reason to choose the Body Scan.

A 6-lead ECG and heart insights

The handle’s electrodes also let the Body Scan record a 6-lead electrocardiogram and screen for atrial fibrillation (AFib), all while you stand on the scale. This is a meaningfully different proposition from the single-lead ECG on most smartwatches, and it is the feature that pushes the Body Scan from “smart scale” toward “home health device.” It also computes a more thorough vascular age estimate. None of this is a substitute for a doctor’s assessment, but as a daily passive screen it is genuinely useful, especially for people managing heart-health risk factors.

Is segmental data actually worth it?

Segmental analysis is the single feature that most cleanly separates these two scales, so it deserves an honest look. For a general user who just wants to know whether they are gaining muscle or losing fat over a training block, a good whole-body number from the Body Comp is plenty. The trend line is what matters, and both scales draw that line well.

Where segmental data earns its keep is in situations with genuine left-right or upper-lower asymmetry. If you are recovering from a knee surgery and want to confirm that the injured leg is rebuilding muscle, or you lift seriously and want to catch a lagging arm before it becomes an imbalance, per-zone readings give you a signal a whole-body figure cannot. Physical therapists, strength athletes and biohackers are the people who will genuinely use it. For everyone else, it is a nice-to-have rather than a reason to spend an extra couple hundred dollars.

The on-scale ECG, explained

An electrocardiogram records the electrical activity of your heart. Most consumer ECGs, including the one on the Apple Watch, are single-lead: they capture one viewing angle of the heartbeat, which is enough to flag an irregular rhythm like AFib but limited in detail. The Body Scan’s 6-lead ECG uses electrodes in both your feet and both hands (via the handle) to capture several angles at once, producing a richer trace.

In practice, the value is convenience and consistency. You are already standing on the scale, so a heart-rhythm check happens as part of your routine rather than requiring a separate deliberate action. It is not a diagnostic tool and it will not replace a clinical 12-lead ECG at a doctor’s office, but for someone with known risk factors, a passive daily screen that nudges them to seek care when something looks off is a real benefit. It is worth noting that ECG availability can depend on regional regulatory clearance, so confirm the feature is active in your market.

Accuracy and the honest caveats

It is worth being clear about what BIA can and cannot do. Bioimpedance is excellent at spotting trends in the same person over time, but the absolute body-fat numbers from any consumer scale, Withings included, should be treated as estimates rather than lab-grade truth. Readings shift with hydration, time of day, and recent meals, so the value comes from weighing yourself under consistent conditions and watching the direction of travel. The Body Scan’s segmental breakdown is more granular than the Body Comp’s, but it is still an estimate, not a DEXA scan.

The nerve-health feature works by measuring your skin’s electrochemical response, essentially reading sweat-gland activity in your feet to flag possible signs of small-fiber nerve issues. Like everything else here, Withings positions it as an indicator, not a diagnosis. Treat any flagged result as a prompt to talk to a clinician, not a verdict.

The Withings+ subscription question

The subscription is the other honest caveat. Withings+ costs about $9.95 a month or roughly $99.95 a year, and new scales include a one-month trial. It unlocks deeper reports and trend analysis, an overall Health Improvement Score, AI-driven insights and, for heart-focused users, optional access to cardiologist-reviewed ECG summaries.

Neither scale is bricked without it. You still get your core measurements, app sync and the headline metrics free forever. But if you want the full experience, particularly the richer cardiovascular reporting that makes the Body Scan compelling in the first place, you should factor the recurring cost into your budget. For a Body Comp buyer chasing value, skipping the subscription after the trial is perfectly reasonable; for a Body Scan buyer who bought the device specifically for heart insights, the subscription is closer to part of the package.

Who each scale suits

Which one should you buy?

Choose the Body Comp if your priority is body composition and general wellness tracking, you want vascular-age and metabolic insights, and you would rather not spend flagship money. It covers what the vast majority of people actually use a smart scale for, and it does so at less than half the price of the Body Scan.

Choose the Body Scan if you specifically want segmental muscle and fat data, or if the on-scale 6-lead ECG and deeper cardiovascular screening genuinely matter to you. Those two capabilities are the entire reason it exists, and they are real. If you do not need them, you are paying a large premium for a handle you will rarely use.

For most households, the Body Comp is the smarter buy and the better value. The Body Scan is the right call for data-driven users, strength athletes, and anyone for whom heart monitoring is a priority. And if longevity tracking is your goal, keep an eye on the newer Body Scan 2 before you decide. Whichever you pick, both slot neatly into the same ecosystem, so your data and app experience will feel identical, even if what the hardware can measure does not.

Frequently Asked Questions

What is the main difference between the Withings Body Scan and Body Comp?

The Body Scan has a retractable handle that enables two features the Body Comp lacks: segmental body composition across five zones (torso, both arms, both legs) and an on-scale 6-lead ECG with AFib screening. Otherwise the two share the same core body-composition and vascular-age capabilities.

How much do the Body Scan and Body Comp cost in 2026?

At the time of writing, the Body Comp lists at around $229.95 and the Body Scan at around $499.95 on the Withings web store. Prices vary with sales and retailer. Withings also announced a Body Scan 2 at roughly $599.95.

Do I need a Withings+ subscription?

No. Both scales work and sync their core metrics without one. Withings+ (about $9.95/month or $99.95/year) unlocks deeper reports, trend analysis and, for the Body Scan, richer cardiovascular reporting and optional cardiologist-reviewed ECG summaries. New scales include a one-month trial.

Are Withings body-fat readings accurate?

They are solid estimates rather than lab-grade measurements. Bioimpedance is best at tracking trends over time in the same person under consistent conditions. Treat absolute body-fat percentages as approximate, and rely on the direction of the trend line rather than any single reading.

Should I wait for the Withings Body Scan 2?

If longevity tracking is your goal, it is worth considering. The Body Scan 2 targets 60-plus biomarkers, adds impedance cardiography and a cuff-free hypertension risk notification, and lists at around $599.95. Note that some ECG and blood-pressure features depend on FDA clearance in the US, so confirm availability before buying.

Can either scale replace a doctor’s visit?

No. Both are wellness and screening tools, not diagnostic devices. Features like the 6-lead ECG, vascular age and nerve-health assessment are designed to flag things worth discussing with a clinician, not to diagnose conditions on their own.
