This is a great question because buying a washing machine isn’t just about the number of people in the house—it’s also about lifestyle, fabric types, washing frequency, and even seasonal differences. Let me break it down from a different angle.

1. Type of Clothes Matter More Than Just Family Size

It’s easy to assume that a family of 4 can manage with a 7kg machine, but the type of clothes you wash makes a huge difference. For example:

• Cotton clothes (which are common in India due to the weather) are light and take up less space in the drum. You can fit a good number of them in a 7kg machine.
• Denim and winter wear like sweaters, jackets, or hoodies are bulkier and will take up a lot of space, meaning you’ll need more wash cycles. If you live in North India where winters are harsh, you may struggle to fit everything into a 7kg drum.
• Sarees, dupattas, and ethnic wear—If your family wears sarees, anarkalis, or heavy kurtas often, these can be delicate and require gentler wash cycles, reducing how much you can fit in one go.

So, while 7kg might seem fine on paper, if your wardrobe includes a mix of thick, bulky clothes and delicate fabrics, you might end up running multiple loads.

2. Drying Time & Space Constraints

Many people overlook this, but the size of the washing machine directly impacts drying time and space management.

• If you have a small balcony or drying area, washing smaller loads more frequently might actually be better because you don’t want to run out of space to dry clothes. A bigger machine means washing everything at once, but if you don’t have enough space to dry them, it’s going to be a headache.
• During monsoons, drying is already a challenge. A 7kg machine means smaller loads, which could dry faster indoors with a fan. However, a bigger load from an 8-9kg machine might take forever to dry without a dryer or proper ventilation.

3. Power and Water Consumption: Hidden Costs

At first glance, a 7kg washing machine seems cost-effective because it's cheaper than an 8kg model. But here’s the catch:

• More frequent washes = more power and water consumption.
• If you have a water tank system (common in apartments and independent houses in India), frequent washes mean faster depletion of stored water.
• If you’re using borewell water, hard water issues can impact the machine’s efficiency, requiring more detergent and potentially reducing lifespan.

In the long run, if you’re running extra cycles just to accommodate all your laundry, you might actually be spending more money on electricity and water than if you had bought a slightly bigger machine in the first place.

4. Future-Proofing Your Purchase

One thing people forget when buying a washing machine is future needs. A 7kg machine might be enough for your current family size, but think about:

• Growing kids—As kids grow, so do their clothing needs. School uniforms, sports jerseys, and extra sets of clothes for tuition or outdoor play will add to the laundry load.
• Guests and extended family visits—In India, it’s common to have relatives stay over for a few days. If that happens, your laundry load will temporarily increase.
• Maid’s clothes (if applicable)—Many households wash their house help’s clothes separately, which could mean an extra cycle every few days.

If you plan to use the machine for the next 7-8 years, investing in a slightly bigger one now might save you from upgrading too soon.

Final Verdict: Who Should Get a 7kg Machine?

A 7kg washing machine is a good choice if:
✅ You have a small drying space and prefer smaller, frequent washes.
✅ Your family mostly wears light cotton or synthetic clothes.
✅ You don’t mind doing bedsheets and towels separately.
✅ You’re okay with running an extra wash cycle occasionally.

But if you:
❌ Have heavy clothes like jeans, jackets, or ethnic wear that take up space.
❌ Want to future-proof your purchase for a growing family.
❌ Prefer washing everything at once to save time and electricity.
❌ Live in a city with hard water issues, which means frequent maintenance.

Then it’s worth stretching your budget for an 8kg or 8.5kg model.

Final Thought

I’d suggest thinking beyond just the number of family members and considering your laundry habits, space, electricity/water costs, and future needs. If your budget allows, getting an 8kg machine might be a smarter long-term investment.

I’d say it depends on your laundry habits. I have a 5-member family (3 adults + 2 kids), and we initially got a 7kg machine thinking it would be enough, but in reality, we ended up doing laundry almost every day. If you have kids who play outdoors and get their clothes really dirty, you might find a 7kg machine a bit small.

We later upgraded to an 8kg one, and now we can comfortably do laundry every 2-3 days without overloading the drum. If you’re okay with frequent washing, 7kg works, but if you prefer fewer washes, you might want to go for an 8kg+ model.

I have been using a 7kg front-load washing machine for the last 5 years for my family of 4, and honestly, it’s manageable. You just need to be smart about how you load it.

• Daily wear like T-shirts, jeans, and undergarments? No problem.
• Bedsheets? Max 2 single ones or 1 double bedsheet at a time.
• Towels? Can fit around 4-5, but that means no room for much else.

If you don’t mind doing separate cycles for bedsheets and heavy clothes, 7kg is sufficient. Otherwise, you might feel limited.

A 7kg washing machine comes with some drawbacks, especially for a family of 4 or 5:

1. Frequent washing – You will need to run it every other day or even daily if you have kids who go through multiple outfits.
2. Limited capacity for large items – Washing blankets, comforters, or even multiple bedsheets can be tricky.
3. Overloading risk – If you try to squeeze in extra clothes, the washing quality suffers, and the machine might not last as long.
4. More power & water usage over time – Since you’re doing multiple washes instead of one big load, you might end up using more electricity and water in the long run.
5. Can be inconvenient for working couples – If both partners work, finding time to do frequent washes can be a hassle.

If you can stretch your budget, it might be worth considering an 8kg+ model, especially if you have a big household.

Honestly, it depends on your lifestyle. If you’re a family of 4-5 and don’t mind running the machine frequently, a 7kg model will do the job. But if you prefer to wash everything in one go, you might find it too small.

One thing I noticed is that with kids, clothes pile up fast. My son comes home from school with his uniform dirty almost every day, so we end up washing clothes more often. Also, in monsoons, when drying takes longer, having a bigger drum helps since you can wash in fewer cycles and dry everything at once.

My advice? If you’re on a budget and don’t mind frequent washes, go for it. Otherwise, an 8kg or 8.5kg machine is a better long-term investment.
