Introduction
Not all steel studs are the same member. C-studs, track, furring channel, and U-channel each have different profiles, different weights per foot, and different jobs — and within each type, seven gauges span a 5× weight range. Choosing the right member at the right gauge is where weight knowledge turns into money: the correct gauge is the lightest one that meets the structural and fire requirements, because every unnecessary mil is steel you bought, shipped, and installed for nothing.
The Steel Stud Weight Calculator gives you the per-foot weight of any designation in pounds and kilograms per meter. This guide covers what those designations describe — member types, gauge selection by application, galvanization, and how profile choice changes the weight on your order. For decoding designations, see the complete guide.
Member Types and Their Profiles
C-studs (S)
The workhorse: a C-shaped section with a web, two flanges, and small stiffening lips. Studs carry vertical loads and provide the nailing surface for drywall. A 362S162-33 (3-5/8″, 20 gauge) weighs about 0.65 lb/ft (0.97 kg/m) — the baseline most estimators know by heart.
Track (T)
U-shaped channel without stiffening lips, used as top and bottom plates. Studs slide into track and are screwed or welded in place. Track of the same depth and gauge runs slightly lighter than the matching stud — budget it at the stud’s per-foot weight for conservative planning, as the estimating guide recommends.
Furring channel and U-channel
Hat-shaped furring channel (for ceilings and wall furring) and plain U-channel (for blocking and bracing) are lighter per foot than studs of comparable size because their developed width is smaller. They still add up on big jobs — a suspended ceiling’s furring grid can total hundreds of pounds — so include them in delivery-weight planning.
Gauge Selection by Application
Gauge choice is driven by wall height, loading, and fire or acoustic requirements — not by preference. The table below gives typical applications; always confirm against the project specifications and your local building authority.
| Gauge (mils) | Weight, 362 series (lb/ft) | Typical applications |
|---|---|---|
| 25 ga (18 mil) | 0.40 | Non-load-bearing interior partitions, standard 8–10 ft heights, light finishes |
| 22 ga (27 mil) | 0.53 | Interior partitions with heavier finishes or taller walls up to ~12 ft |
| 20 ga (33 mil) | 0.65 | The commercial default: partitions, soffits, chase walls; most common gauge ordered |
| 18 ga (43 mil) | 1.01 | Tall partitions, shaft walls, walls with heavy wall-hung equipment |
| 16 ga (54 mil) | 1.28 | Structural interior framing, tall curtain walls (engineered) |
| 14 ga (68 mil) | 1.60 | Load-bearing walls, headers, engineered assemblies |
| 12 ga (97 mil) | 2.24 | Heavy structural framing, engineered only |
The cost implication is direct: stepping from 20 to 16 gauge nearly doubles the steel — and roughly doubles the material cost. Weight scales with thickness exactly as the weight formula predicts, so there are no surprises — only the question of whether the application justifies the steel. Overspecifying “to be safe” is one of the most expensive habits in framing, and it doesn’t substitute for engineering where engineering is required.
Web Depth: How Size Changes Weight
Deeper studs weigh more per foot at the same gauge because there’s simply more steel in the cross-section. Comparing 20-gauge profiles:
| Profile (20 ga / 33 mil) | Depth | Approx. weight (lb/ft) | Approx. weight (kg/m) |
|---|---|---|---|
| 162S162-33 | 1-5/8″ (41 mm) | 0.43 | 0.64 |
| 250S162-33 | 2-1/2″ (64 mm) | 0.55 | 0.82 |
| 350S162-33 | 3-1/2″ (89 mm) | 0.63 | 0.94 |
| 362S162-33 | 3-5/8″ (92 mm) | 0.65 | 0.97 |
| 400S162-33 | 4″ (102 mm) | 0.74 | 1.10 |
| 600S162-33 | 6″ (152 mm) | 0.94 | 1.40 |
| 800S162-33 | 8″ (203 mm) | 1.14 | 1.70 |
Depth is usually dictated by insulation, plumbing, or acoustic requirements rather than weight — but when two depths both satisfy the design, the shallower one saves steel on every linear foot of the job.
Galvanization and Coatings
Most interior studs carry a light galvanized coating (G40 is common for drywall framing); exterior and high-moisture applications call for heavier coatings (G60, G90). The coating adds a small amount of weight — typically 1–3% — which published weight tables already include. You don’t need to adjust calculator results for coating, but you do need to specify the right coating for the environment: using interior-coated studs in a damp location is a durability failure, not a weight question. Your supplier stocks the coating grades your market requires.
Length and Availability
Standard stud lengths run 8, 10, 12, 14, and 16 feet (2.44–4.88 m); not every gauge is stocked in every length at every supplier. Longer lengths reduce splicing and waste on tall walls but complicate delivery and handling — a 16-foot 12-gauge stud weighs about 36 lb (16.3 kg) and needs two people or mechanical help in tight spaces. Confirm stocked lengths before finalizing the takeoff, because a length change ripples through piece counts, waste, and the delivery plan covered in the pro tips guide — and the case study shows how those ripples play out on a full order. If your specified length isn’t stocked, the FAQ covers how to adapt the takeoff to what’s available.

Frequently Asked Questions
What’s the most common steel stud gauge?
20 gauge (33 mil) 3-5/8″ C-stud is the commercial interior default — the best balance of stiffness, weight (0.65 lb/ft), and cost for standard partitions.
When do I need 16 gauge or heavier?
For structural applications, tall walls, or heavy loads — and those applications require engineering. Never upsize gauge as a substitute for a structural design.
Does galvanized coating change the weight?
Only by 1–3%, which published tables already include. Specify coating for corrosion protection, not weight.
Can I use a deeper stud instead of a heavier gauge?
Sometimes — depth adds stiffness efficiently — but it’s a design decision, not a field substitution. Confirm with the drawings or engineer.
What’s the difference between C-stud and track weight?
Track is slightly lighter per foot than the matching stud due to its simpler profile. Using stud weight for track in estimates is a safe conservative planning figure.
