22 AWG vs 24 AWG Ethernet Cable: Which Performs Better?
Why Does Wire Gauge Matter in Ethernet Cables?
If you have ever bought an Ethernet cable and seen the term "22 AWG" or "24 AWG" on the box, you may have wondered — what does this mean, and does it really affect my internet speed or network quality?
The short answer is: yes, it does matter — especially for longer cable runs, Power over Ethernet (PoE) devices, and high-performance setups. In this guide, we break down everything you need to know about 22 AWG vs 24 AWG Ethernet cables in simple, easy-to-understand language.
What Is AWG and How Does It Work?
AWG stands for American Wire Gauge — a standard system used to measure the thickness (diameter) of wire conductors inside a cable.
Here is the important thing to remember:
Key Rule: The lower the AWG number, the THICKER the wire. 22 AWG = Thicker wire | 24 AWG = Thinner wire Thicker wire = Less resistance = Better signal over long distances |
Think of it like a water pipe. A wider pipe (22 AWG) lets more water flow with less pressure loss. A narrower pipe (24 AWG) is fine for short distances but struggles over longer runs.
22 AWG vs 24 AWG: Side-by-Side Comparison
Here is a quick comparison table so you can see the key differences at a glance:
Feature | 22 AWG | 24 AWG | Winner |
|---|---|---|---|
Wire Diameter | 0.644 mm | 0.511 mm | 22 AWG (Thicker) |
Resistance (Ω/km) | ~54 Ω/km | ~86 Ω/km | 22 AWG (Lower) |
Max Distance | 100 m+ | 100 m | 22 AWG |
PoE Support | Excellent | Good | 22 AWG |
Flexibility | Less flexible | More flexible | 24 AWG |
Cable Size | Bulkier | Slimmer | 24 AWG |
Cost | Higher | Lower | 24 AWG |
Best Use | Long runs, high PoE | Shorter runs, patching | Depends on need |
Performance: Which One is Faster and More Reliable?
Both 22 AWG and 24 AWG cables can deliver the same maximum speed when used within their ideal distance range. However, performance differences start to show in specific situations.
Signal Strength Over Distance
Thicker 22 AWG wire has lower electrical resistance (around 54 Ω/km) compared to 24 AWG (around 86 Ω/km). This means:
22 AWG maintains stronger signal strength over longer cable runs
24 AWG may experience slightly higher signal loss (attenuation) on runs approaching 100 metres
For runs under 30 metres, both perform equally well
Power over Ethernet (PoE) Performance
This is where 22 AWG truly shines. Devices like IP cameras, wireless access points, and VoIP phones use PoE to receive both data and power through the same cable.
Because 22 AWG has lower resistance, it generates less heat when carrying power. This is critical for:
High-power PoE++ devices (IEEE 802.3bt, up to 90W)
Dense cable bundles in server rooms or ceiling trays
Long PoE cable runs where voltage drop becomes an issue
|
Distance: How Far Can Each Cable Run?
The TIA/EIA-568 standard sets the maximum cable run for Ethernet at 100 metres (328 feet). Both 22 AWG and 24 AWG can reach this limit, but with a key difference in real-world performance:
22 AWG: Comfortably maintains signal quality at or beyond 100 metres. Lower resistance means less signal degradation.
24 AWG: Performs well up to 100 metres in standard conditions. On longer runs or in environments with electrical interference, performance may drop.
For most home and small-office setups, 24 AWG is perfectly fine since cable runs rarely exceed 50 metres. However, for commercial buildings or long structured cabling runs, 22 AWG is the safer choice.
Installation: Which Cable Is Easier to Work With?
This is one area where 24 AWG has a practical advantage:
24 AWG is thinner and more flexible — easier to route through walls, conduit, and tight spaces
22 AWG is thicker and stiffer — requires more care when bending around corners or routing through confined areas
22 AWG cables are slightly heavier, which can matter in large commercial cable tray installations
24 AWG is more commonly found in pre-made patch cables and stranded varieties
Installation Tip: For in-wall or in-ceiling runs (permanent horizontal cabling), choose solid core 22 AWG or 23 AWG. For patch cables and short equipment connections, stranded 24 AWG is more practical. |
Which AWG Goes With Which Ethernet Cable Category?
Understanding AWG also helps when choosing between Cat5e, Cat6, Cat6A, and Cat7 cables. Here is how the AWG maps to popular cable categories:
Cable | AWG | Bandwidth | Speed/Distance | PoE Support | Best For |
|---|---|---|---|---|---|
Cat5e | 24 AWG | 100 MHz | 1 Gbps / 100m | PoE / PoE+ | Home, small office |
Cat6 | 23 AWG | 250 MHz | 10 Gbps / 55m | PoE / PoE+ | Offices, SMBs |
Cat6A | 23 AWG | 500 MHz | 10 Gbps / 100m | PoE++ | Enterprise, data centres |
Cat7 | 23 AWG | 600 MHz | 10 Gbps / 100m | PoE++ | Specialized / shielded |
As the table shows, Cat5e typically uses 24 AWG, while Cat6 and above often use 23 AWG or even 22 AWG for improved performance. This is why Cat6A and Cat7 handle high-power PoE and 10 Gbps connections over full-length 100-metre runs better than Cat5e.
Cat5e, Cat6, Cat6A, and Cat7: Which Cable Should You Buy?
Cat5e — The Reliable Entry-Level Option
Cat5e (Category 5 Enhanced) uses 24 AWG conductors and supports up to 1 Gbps over 100 metres with a bandwidth of 100 MHz. It is the most widely installed Ethernet cable in the world and a cost-effective choice for home networks and small offices running standard internet connections.
It supports PoE (15.4W) and PoE+ (30W), making it suitable for basic IP cameras and access points. For most everyday tasks — browsing, video streaming, and general file sharing — Cat5e delivers reliable performance at an affordable price.
Cat6 — The Smart Upgrade for Future-Ready Networks
Cat6 (Category 6) commonly uses 23 AWG conductors and delivers 250 MHz bandwidth. It supports 10 Gbps at up to 55 metres and Gigabit speeds over the full 100-metre run. The thicker conductors and often-included internal spline separator reduce crosstalk significantly compared to Cat5e.
Cat6 is the go-to recommendation for most new installations today — it offers a meaningful upgrade over Cat5e at a modest price increase and handles PoE/PoE+ loads more efficiently thanks to its lower conductor resistance.
Cat6A — Best for Full 10 Gbps and High-Power PoE
Cat6A (Augmented Category 6) is the gold standard for enterprise networking. With 23 AWG conductors and a 500 MHz bandwidth, it supports a full 10 Gbps over the entire 100-metre run — not just 55 metres like Cat6. It is also the recommended cable for PoE++ (IEEE 802.3bt up to 90W) deployments.
Cat6A is the right choice when planning for high-density wireless access points, IP security camera systems, or any environment where 10 Gigabit Ethernet at full building distances is required.
Cat7 — Shielded Performance for Demanding Environments
Cat7 features shielded twisted pairs (S/FTP) and 23 AWG conductors with a 600 MHz bandwidth. It is designed for environments with high electromagnetic interference (EMI) — such as industrial facilities, hospitals, or buildings with heavy electrical equipment.
Note: Cat7 uses proprietary GG45 or TERA connectors in its fully compliant form and is not officially recognized by TIA/EIA standards for most commercial cabling. For standard enterprise use, Cat6A remains the industry-preferred option. Cat7 is a specialised choice for specific high-interference scenarios.
When Should You Choose 22 AWG vs 24 AWG?
Choose 22 AWG when: • Cable runs exceed 55–80 metres • You are installing PoE++ devices (cameras, WAPs, IP phones) • Cables will be bundled together in conduit or cable trays • You need maximum long-term durability in a commercial setup |
Choose 24 AWG when: • Cable runs are under 30–50 metres • You need patch cables or short flexible connections • Installing in tight spaces where flexibility matters • Working on a budget for home or small office use |

Frequently Asked Questions
Q1: Is 22 AWG better than 24 AWG for Ethernet?
22 AWG is better for long cable runs and high-power PoE applications because its thicker conductor means lower resistance and less signal loss. For short runs under 30–50 metres, 24 AWG performs equally well and is more cost-effective.
Q2: Does AWG affect internet speed?
AWG does not affect speed directly within normal distance limits — both can support Gigabit or 10 Gbps speeds. However, over longer distances or in PoE setups, thicker wire (lower AWG) delivers more stable performance.
Q3: What AWG is Cat6A?
Cat6A typically uses 23 AWG conductors, which sit between 22 AWG and 24 AWG in thickness. This gives it excellent resistance to signal loss and strong PoE++ capability over the full 100-metre run.
Q4: Can I mix 22 AWG and 24 AWG cables in the same network?
Yes, technically you can. However, for consistency and to avoid troubleshooting complications, it is best to standardise on one AWG and one cable category throughout your installation.
Q5: What is the best Ethernet cable for PoE cameras?
For PoE and PoE+ cameras (up to 30W), Cat5e or Cat6 with 23–24 AWG is sufficient on shorter runs. For PoE++ cameras (up to 90W) or runs exceeding 50 metres, Cat6A with 23 AWG is strongly recommended.
