Hacoo size guide: check measurements before ordering

Looking for a Hacoo size guide before placing an order? Choosing the right size can sometimes be confusing, particularly when different products use different sizing systems or measurements.

The most important thing to remember is that there isn’t one size rule that works for every Hacoo product. Rather than assuming your usual UK or EU size will always fit, it’s worth checking the information provided on the individual product listing before ordering.

This Hacoo size guide covers the main things to check before ordering, including product measurements, footwear sizing and customer reviews.

1. Do Hacoo Sizes Run Small or Large?

There isn’t a single answer that applies to every Hacoo product.

Sizing can vary between products, so one item may fit as expected while another could fit differently even if both show the same labelled size.

That’s why we wouldn’t recommend automatically ordering a size up or down.

Instead, check the sizing information for the specific product you’re considering.

💡 BEST FINDS tip: Don’t choose a different size simply because somebody else’s Hacoo item ran small or large. Check the individual listing first.

2. Check the Product Size Guide Before Ordering

Before choosing S, M, L or XL, check the size information provided on the product page. On Hacoo, tap “What’s My Size?” next to the available sizes to open the product’s size chart.

The chart can show measurements such as shoulder, chest, length and sleeve, and you can switch between centimetres and inches.

Rather than assuming your usual size will fit, compare these measurements with a similar item you already own that fits you well. For example, when buying a jacket, compare its chest, shoulder, sleeve and length measurements with one of your own jackets.

Also allow for the measurement tolerance stated on the product page — in this example, Hacoo notes that a 1–3 cm difference can occur due to manual measurement.

💡 BEST FINDS tip: Focus on the actual measurements rather than just the S/M/L/XL label.

Tap “What’s My Size?” on the Hacoo product page to view the size chart.

Compare the product measurements with your own before choosing a size. You can switch between CM and INCH.

3. How to Choose Your Hacoo Clothing Size

For clothing, don’t rely only on the size label. The measurements shown in the product’s size chart are usually much more useful when deciding what to order.

Start with the measurements that matter most for the type of clothing you’re buying. For T-shirts, jumpers and jackets, check the chest and shoulder measurements. For trousers and shorts, pay particular attention to the waist and hip measurements. Length and sleeve measurements can also help you judge how the item is likely to fit.

One of the easiest ways to do this is to take a similar item from your wardrobe that already fits you well, measure it, and compare those measurements with the Hacoo size chart.

For example, if your favourite jacket measures approximately 120 cm around the chest, look at the product chart and identify which available size has the closest measurement rather than automatically choosing the size you normally buy elsewhere.

💡 BEST FINDS tip: If you’re between two sizes, look at the other measurements too — particularly length, shoulders and sleeves — before deciding. Going up a size may give you more room in one area but also make the item longer or wider elsewhere.

4. How to Choose Your Hacoo Trainer or Shoe Size

Shoe sizing can vary between products too, so don’t assume that the size you normally wear will automatically be the right size on Hacoo.

For trainers and shoes, check the size chart on the individual product page before ordering. Some Hacoo listings provide the recommended foot length in millimetres (mm) alongside each EU size.

The sizing information available can differ between products. Some listings provide a foot-length measurement, while others may provide less detailed sizing information. Always check what is available on the specific product page you’re ordering from.

For example, the product shown below provides a chart matching EU sizes to foot measurements.

How to measure your foot

Hacoo also provides instructions for measuring your foot:

1. Stand on a sheet of paper while wearing the type of socks you would normally wear with the shoes.
2. Draw around the outline of your foot.
3. Measure the maximum length of your foot.
4. Compare this measurement with the Foot (mm) measurement shown in the product’s size chart.

It’s worth measuring both feet and using the longer measurement when comparing against the chart.

💡 BEST FINDS tip: Focus on the foot measurement, not just the EU size. Don’t automatically size up or down based on another Hacoo purchase — check the size chart for the specific pair you’re ordering.

Hacoo recommends tracing your foot and measuring its maximum length before comparing it with the product size chart.

5. Check Customer Reviews Before Choosing Your Size

Before ordering, it’s also worth checking the customer reviews for the specific product you’re considering.

Some Hacoo product pages summarise how previous buyers found the fit, showing the percentage of reviewers who considered the item small, true to size or large.

This can be particularly useful when deciding between two sizes. However, don’t rely on the overall percentage alone — read some of the individual reviews too.

For example, in the product shown below, 86% of reviewers rated the fit as true to size, while 5% considered it small and 9% large.

Some Hacoo listings show whether previous buyers found the product small, true to size or large.

One individual reviewer who ordered an EU 40 nevertheless reported that the shoe fitted smaller than expected.

Individual reviews can provide additional information about how a particular size fitted the buyer.

This is a good reminder that everyone’s fit can be slightly different.

💡 BEST FINDS tip: Use reviews alongside the product’s size chart. If several buyers mention the same sizing issue, take that into account — but always compare the product measurements with your own first.

6. Is There a Hacoo UK or EU Size Conversion Chart?

Hacoo does not appear to provide one universal size conversion chart that can be applied to every product.

The sizing information available can also differ between individual listings. Some clothing products provide detailed measurements such as chest, shoulder, sleeve and length, while some footwear listings provide EU sizes alongside foot length in millimetres. Other products may provide less sizing information.

Because of this, we wouldn’t recommend using a single Hacoo-to-UK or Hacoo-to-EU conversion table for everything on the platform.

Instead, check the sizing information available on the individual product page first. Where measurements are provided, use those rather than relying only on the labelled size.

If detailed measurements aren’t available, customer reviews become particularly useful. Check whether previous buyers describe the product as small, true to size or large, and look for comments from people who purchased the size you’re considering.

💡 BEST FINDS tip: If a product doesn’t provide enough sizing information and the reviews don’t give you confidence about the fit, consider choosing another listing with clearer measurements and more sizing feedback.

7. Hacoo Size Guide: Quick Checklist Before Ordering

Before ordering clothing, trainers or shoes on Hacoo, take a minute to check the sizing information for the individual product.

Before you order:

1. Don’t rely only on your usual size. Sizing can vary between different Hacoo products.
2. Open the product’s size guide, where one is available.
3. Check the actual measurements rather than focusing only on S, M, L, XL or the EU size.
4. For clothing, compare measurements such as chest, shoulder, sleeve and length with something you already own.
5. For shoes, check the foot-length measurement if the listing provides one.
6. Read the customer reviews, particularly the sizing feedback and comments from buyers who ordered the size you’re considering.
7. If the listing doesn’t provide enough sizing information, consider another listing with clearer measurements or more customer feedback.

💡 BEST FINDS tip: Spending an extra minute checking the product measurements and reviews before ordering can make choosing the right size much easier.

8. Frequently Asked Questions About Hacoo Sizing

Do Hacoo sizes run small?

Not necessarily. There isn’t one sizing rule that applies to every Hacoo product. Some items may fit smaller or larger than expected, while others may be true to size. Check the size information and customer reviews for the specific product before ordering.

Should I size up on Hacoo?

We wouldn’t recommend automatically sizing up. Instead, check the measurements provided on the individual product listing and compare them with your own measurements or an item you already own that fits well.

Are Hacoo shoe sizes true to size?

It depends on the individual pair. Some Hacoo footwear listings provide a size chart with recommended foot length, while others provide less detailed sizing information. Check the information available for the specific product and use customer sizing reviews as additional guidance.

How do I know what size to order on Hacoo?

Start with the product’s own size guide. For clothing, compare measurements such as chest, shoulder, sleeve and length. For shoes, check the recommended foot length where available. Customer sizing reviews can provide additional guidance.

Can I use my normal UK size on Hacoo?

Your normal UK size can be a useful starting point, but don’t assume it will translate directly to every Hacoo product. Hacoo does not provide one universal UK conversion chart for all listings, so the individual product measurements should be your main reference.

Does Hacoo have a size chart?

Some Hacoo products have detailed size charts, but the information provided varies between listings. Clothing charts may include measurements such as chest, shoulder and length, while some footwear listings show EU sizes alongside foot length.

What should I do if a Hacoo product doesn’t have enough sizing information?

Check the customer reviews for comments about whether the product fits small, true to size or large. If there still isn’t enough information to choose confidently, consider another listing with a clearer size guide and more customer feedback.
