The quote looked like a bargain. The coil of 7/29 was cheaper than at every other shop, the dealer said it was “full copper”, and the label said 90 meters. Halfway through the wiring, the electrician needed two extra coils, the sockets on the kitchen circuit started to feel warm, and the “saving” was gone.
This is one of the most common ways buyers in Pakistan overpay for wire: not by paying a high price, but by paying a normal-looking price for a coil that contains less copper or less length than it claims. The lower number at the counter hides a higher cost per meter of real copper.
This guide shows you how to see past the coil price, calculate what you are really paying per meter, spot the four common ways a coil can contain less than it should, and make sure every rupee you spend buys real, full-length copper.
Why the Price Per Coil Can Mislead You
Wire is sold by the coil, so that is the number buyers compare. But a coil is only a container. What you are really buying is a length of copper conductor of a certain size, with insulation around it.
If two coils have the same price but one is shorter, has thinner strands or uses a weaker conductor, you are paying the same money for less. The only fair comparison is what you pay for each meter of genuine, full-size copper wire.
This matters more than it seems. A house needs many coils across several sizes, and a small shortfall on each coil adds up across the whole order. A few meters missing from every coil can mean buying one or two extra coils for the same job, which wipes out the saving that made the cheaper coil attractive in the first place.
How to Calculate Wire Price Per Meter
The calculation is simple, and it is the single most useful thing you can do before you buy.
Price per meter = coil price ÷ real coil length in meters
The important word is “real”. Use the length you have checked, not just the length printed on the label.
Worked Example: The “Cheaper” Coil
The figures below are example units only, not real market prices, to show how the calculation works.
| Coil A | Coil B | |
|---|---|---|
| Coil price (example units) | 100 | 95 |
| Label length | 90 m | 90 m |
| Real length | 90 m | 81 m |
| Price per meter | about 1.11 | about 1.17 |
Coil B looks 5% cheaper, but it is 9 meters short. Per meter, it is actually more expensive. Across a whole house that needs many coils, the difference adds up to extra coils, extra money and extra delays.
The Four Ways a Coil Can Contain Less Copper
When a coil is noticeably cheaper than the market, the saving usually comes from one or more of these four places.
1. Short Coil Length
The coil is marked 90 meters (97 gaz) but measures less. This is the easiest cut to make and the hardest to notice at the counter. Ask the dealer whether you can measure a coil, or buy from a manufacturer that guarantees full length.
2. Undersized Strands
The wire is sold as 7/29 or 7/36 but made with strands slightly thinner than the size requires. It looks almost the same, but every meter contains less copper. It carries less current and runs hotter, so you pay for one size and get the performance of a smaller one.
3. Mixed Metal or Copper-Clad Aluminium
The conductor is not pure copper all the way through. Copper-clad aluminium has an aluminium core with a thin copper coating, so it looks like copper on the outside. Read copper or aluminium wire: 7 differences every homeowner in Pakistan should know to understand why this matters.
4. Thin or Recycled Insulation
The PVC around the copper is thinner than it should be, or made from recycled material. It lowers the cost but cracks, hardens or melts sooner, especially inside hot roofs and walls.
Simple Checks Before You Pay
You do not need a laboratory to protect yourself. These checks take a few minutes at the dealer.
- Read the printing. Good wire shows the brand, size and voltage clearly along the insulation.
- Count the strands. 7/29 should have 7 strands, 3/29 should have 3.
- Compare strand thickness. Hold a sample next to a genuine wire of the same size.
- Check the cut end. The conductor should be the same copper colour all the way through, with no silver core.
- Compare the weight. A coil of the same size and length that is noticeably lighter has less copper.
- Ask about length. Confirm the coil is a full 90 meters (97 gaz), and measure one if possible.
- Calculate price per meter. Use the real length, not the label.

The Hidden Costs of Wire With Less Copper
A coil with less copper does not only cost more per meter. It keeps costing money for years after it is installed.
- Higher electricity bills. Thinner copper wastes more energy as heat.
- Extra coils mid-job. Short coils mean unplanned purchases and delays.
- Burnt sockets and switches. Undersized wire heats up at terminals.
- Nuisance breaker trips. Overloaded circuits trip more often.
- Rewiring costs. Replacing hidden wiring means breaking walls.
Benefits of Paying for Real Copper and Full Length
Paying a fair price for genuine wire gives you more for every rupee.
- True value per meter. Every meter you pay for is in the coil.
- The performance you paid for. True gauge copper carries its rated current.
- Lower running cost. Less heat means less wasted electricity.
- Safer home. Cool connections and good insulation reduce fire risk.
- Accurate estimates. Full coils mean your quantity plan works. See our house wiring coil calculator.
Common Mistakes That Lead to Paying for Less Copper
Most buyers who overpay make one of these mistakes.
- Comparing price per coil only. Always compare per meter.
- Trusting the label without checking. Size and length can be printed on any coil.
- Choosing the lowest quote by default. A very low price usually has a reason.
- Buying unbranded wire. No name means no one is responsible for the size or length.
- Ignoring the conductor. Copper colour on the outside does not mean copper inside.

For every size in mm², see our electric wire size chart. Always confirm with a qualified electrician for your exact load and installation.
Why Buyers Across Pakistan Choose Thrive Cables for Full-Length Pure Copper Wire
Thrive Cables manufactures single core wire at its facility in Lahore with pure copper conductors, true-gauge strands and fire-retardant PVC insulation. Every coil is a full 90 meters (97 gaz), so the price you pay per coil is the price you pay for every meter of real copper.
Frequently Asked Questions About Paying for Less Copper
These are the questions buyers ask most often about wire value.
How do I calculate the price of wire per meter?
Divide the coil price by the real length of the coil in meters. A full coil is 90 meters, so its price per meter is the coil price divided by 90; a short coil is divided by its smaller real length.
How can I tell if a wire coil is short?
Ask to measure a coil, compare its weight with a full coil of the same size, and buy from a manufacturer that guarantees a full 90 meters (97 gaz).
Why is undersized wire dangerous?
Undersized wire has less copper than its label suggests, so it carries less current and heats up under load. That heat can damage insulation, sockets and switches.
Is cheap wire always low quality?
Not always, but a price far below the market usually comes from less copper, a shorter coil, mixed metal or thin insulation. Check the coil before you buy.
What is the price of full-length copper wire in Pakistan?
Wire price changes with the copper price, so it varies from week to week. Current price on request. Contact Thrive Cables for the latest price, including wholesale price for dealers and contractors.
Conclusion
Paying more for less copper rarely looks expensive at the counter. It hides in short coils, thinner strands, mixed metal and thin insulation, and it shows up later in extra coils, higher bills and burnt fittings.
The rule of thumb is simple: compare price per meter using the real length, check the strands, colour and weight, and buy pure copper from a manufacturer that guarantees full length. Then confirm your wiring plan with a qualified electrician for your exact load and installation.
