How Much Should You Weigh If You’re 5’8? | BMI Range

If you’re 5’8, the practical way to set a weight target is to pair BMI with simple waist checks and real-world health markers. BMI anchors the numbers. Waist and fitness show how that weight sits on your body. This guide gives you the ranges, fast ways to check your own numbers, and smart goals that don’t ignore muscle, age, or build.

How Much Should You Weigh If You’re 5’8? By BMI And Beyond

The body mass index translates height and weight into a single number. At 5’8 (68 in, 1.73 m), the healthy BMI band of 18.5–24.9 lands at roughly 122–164 lb (55–74 kg). That’s the evidence-based “green zone” where risk tends to be lower for most adults. Still, BMI doesn’t separate fat from muscle or show where fat sits. That’s why this page also flags waist targets and everyday signs of good health.

Quick Math For 5’8 (Why The Range Is What It Is)

Weight is BMI × height². With height at ~1.73 m, BMI 18.5 maps to ~55 kg (≈122 lb) and BMI 24.9 maps to ~74 kg (≈164 lb). Numbers outside that band move you into other categories. The table below lists the full spread, including overweight and the three obesity classes used in clinical practice.

Weight Ranges For 5’8 By BMI Category

BMI Category	Weight (kg)	Weight (lb)
Underweight < 18.5	< 55.2	< 122
Healthy 18.5–24.9	55.2–74.3	122–164
Overweight 25.0–29.9	74.6–89.2	165–197
Obesity Class 1 (30.0–34.9)	89.5–104.1	197–229
Obesity Class 2 (35.0–39.9)	104.4–119.0	230–262
Obesity Class 3 (≥ 40.0)	≥ 119.3	≥ 263
Mid-Healthy Check (BMI ≈ 22)	~65.6	~145

Healthy Weight For 5’8 Adults: Charts And Checks

Charts are a starting point. Your best target blends three pieces: BMI range, waist measures, and health status. Use the steps below to set a number you can keep and feel good at.

Step 1 — Confirm Your BMI Number

Plug height and weight into a trusted calculator to get your BMI and see its category. The CDC page lists adult categories used across clinics and research. Link: CDC BMI categories. Those cutoffs define the table you saw above.

Step 2 — Add A Waist Measure

BMI alone can miss risk when fat sits mostly around the belly. A quick fix is to track waist. Two options are useful:

• Waist-to-height ratio (WHtR): aim for a waist under half your height. At 5’8, that’s a waist under ~34 in (~86 cm).
• Waist circumference thresholds: many clinical guidelines flag raised risk at ≥102 cm (men) and ≥88 cm (women). Link: NHLBI BMI & waist guidance.

These waist checks pair well with BMI because they reflect where fat sits, not just how much you weigh.

Step 3 — Look At Fitness, Health Labs, And Symptoms

Two people at the same weight can have very different health pictures. Add simple signals:

• Strength and stamina: can you brisk-walk 30 minutes and perform basic strength moves twice a week without strain?
• Labs and vitals: blood pressure, fasting glucose or A1C, HDL, triglycerides.
• Daily comfort: sleep quality, joint comfort, energy across the day.

What If You Lift Or Play A Power Sport?

Muscle is dense. If you carry more muscle, your BMI may land in the overweight band while your waist and labs look great. In that case, keep your WHtR below 0.5 and track performance trends. That’s a better compass than chasing a lower scale number just to “fit” the chart.

How To Pick A Personal Target If You’re 5’8

Use the flow below to settle on a smart number and a safe pace.

Pick A Starting Target

Scan the healthy band (122–164 lb). Choose a point that fits your frame and goals. Many adults feel balanced near the middle of the band (around 145 lb) because it leaves room for muscle while keeping WHtR under 0.5 for most builds. That said, if you’re smaller-framed, the low end can feel better; if you’re taller-framed in the shoulders and hips, the top end may fit.

Set A Safe Rate

Change in small steps. A swing of ~0.5–1 lb per week is a steady clip for most. Faster cuts can trim muscle and stall progress. If you’re gaining, a lean gain of ~0.25–0.5 lb per week helps add muscle without pushing waist past targets.

Track With Two Numbers, Not One

Log weight weekly and waist monthly. If weight stalls but waist trims, you’re still winning. If weight drops and waist grows, reassess your plan; you may be losing muscle and shifting fat upward.

Why BMI Is Useful—And Where It Falls Short

BMI is quick, cheap, and well studied. It’s reliable at the population level and a decent first pass for individuals. But it doesn’t separate fat, muscle, or bone, and it can miss fat distribution. The CDC explains these strengths and limits plainly on its overview pages. Pairing BMI with waist checks plugs the biggest blind spot.

Common Edge Cases At 5’8

• Endurance build: lower scale weight, easy cardio, but a waist that’s higher than half height. Action: keep weight steady, bring waist down with strength work and protein timing.
• Power build: scale weight in the high healthy or low overweight band, but a trim waist and strong labs. Action: hold weight; push performance.
• Post-diet rebound: big drop on the scale, then a stall. Action: raise protein, lift twice weekly, and keep a small calorie gap rather than an aggressive cut.

Sample Targets And What They Mean

Here are sample targets tied to common goals. Pick one that matches your season of life and time budget.

If You Want General Health And Ease

Choose a number in the healthy band and lock in a waist under half your height. Keep three habits steady: a daily step goal, protein at each meal, and two short strength sessions per week. That mix holds weight steady while keeping your belt size honest.

If You Want Leaner Looks Without Losing Strength

Start near the middle of the band and aim for a slow trim in waist. Keep protein high and favor compound lifts. If the scale barely moves but your belt tightens a notch, you’re moving the right tissue.

If You’re Rebuilding After Time Off

Pick an easy starting number at the high end of healthy. Let routine settle in for a month. When sleep and steps are consistent, nudge weight down in small steps while guarding strength sessions. That trims waist without the burnout loop.

Waist Targets For 5’8 (Simple Benchmarks)

At 5’8, these waist benchmarks help you read your progress. Use a soft tape at the narrowest point between ribs and hips, relaxed and level, after a normal exhale.

Measure	Target	What It Means
Waist-To-Height Ratio	< 0.50	Keep waist under ~34 in (86 cm) at 5’8 for lower risk
Waist (Men)	< 102 cm (~40 in)	Above this, many guidelines flag raised cardiometabolic risk
Waist (Women)	< 88 cm (~35 in)	Above this, many guidelines flag raised cardiometabolic risk
Example At BMI ≈ 22	~31–33 in	Common waist band for mid-healthy builds at 5’8

FAQ-Style Clarity Without The Fluff

Does The “Perfect” Number Exist?

No single number works for every 5’8 adult. Land in the healthy band, keep your waist under half your height, and judge the rest by energy, labs, and how you move through your day.

What If My Frame Is Smaller Or Larger?

Frame size shifts comfort inside the band. Smaller frames often feel best at the lower third. Larger frames can hold the upper third without strain, as long as the waist stays in range and fitness markers look good.

How Often Should I Recheck?

Weigh weekly and measure waist monthly. Revisit goals each season or after life changes—new job schedule, new sport, or a shift in sleep.

Putting It All Together For A 5’8 Goal

If you came here asking, How Much Should You Weigh If You’re 5’8? you’ve now got the numbers and the context. The healthy range sits at roughly 122–164 lb, with BMI as the anchor. Keep your waist under half your height to sharpen the picture. From there, tune the target to your frame and your day-to-day life. Small, steady steps win.

Method Notes And Sources

BMI categories and wording follow the CDC’s adult guidance. See the CDC BMI categories page for definitions used by clinics and researchers. Waist thresholds reflect common clinical cut points summarized by the National Heart, Lung, and Blood Institute; see NHLBI BMI & waist guidance. WHtR “less than half your height” is a simple, widely adopted screen that complements BMI and aligns with many public-health tools.

Bottom Line For 5’8 Adults

Pick a target in the healthy band, guard your waist, and build simple habits that stick. The scale is one tool. Your belt, your breath, and your daily performance are the tie-breakers.
