Size guide | Pioneer


Instructions and video below on how to measure for your belt size. Learn the correct way to measure to find the right size for your belt.

  1. Use of a pliable or seamstress tape is preferred.
  2. Measure around your naval or where you are going to wear the belt. 
  3. Do not “suck in” or brace, measure in a relaxed state, then pull the measuring tape tight. It is important that you pull the tape tight and use this tight measurement to choose your correct belt size. If you do not pull the tape tight then the belt may be too big for you.
  4. You can also measure your existing belt to ascertain the size you will need (please see the video below).
  5. Take that measurement and use the size guide on the belt you are interested in ordering.
    • X-Small : 22″- 31″ / 55.9cm - 78.7cm
    • Small : 27″- 36″ / 68.6cm - 91.4cm
    • Medium : 31″- 40″ / 78.7cm - 101.6cm
    • Large : 35″- 44″ / 88.9cm - 111.7cm
    • X-Large : 39″- 48″ / 99cm - 121.9cm
    • XX-Large : 43″- 52″ / 109.2cm - 132cm
    • XXX-Large : 47″- 56″ / 119.4cm - 142.2cm
  6. Remember please take into consideration weight loss or gain.

The vast majority of sizing issues we see are belts being ordered one size too large. It is important to take a tight measurement where you will wear your belt or if you have an existing belt you can measure that (Matt explains how in the video below).

Weightlifting / powerlifting belts are worn well above where you wear your shorts or trousers, this means they are worn above the hip bones. Most people are inclined to use their shorts / trouser size or waist measurement for a weightlifting belt. This often ends up with the belt not fitting correctly.

If you have any doubt to your belt size, please contact us as we will be more than happy to help.

Pioneer can make belts larger than XXXL. If you need a larger belt then please contact us.

PLEASE NOTE - For Pioneer Hybrid / Velcro Belts the sizing is different to above. XS : 19-25", S : 24-30", M : 29-35", L : 34-40", XL : 39-45" and XXL 44-50".

Best and Strongest Smelling Salts Going!

Essential headband

The only brand I wear and I'd recommend!

Beautifully crafted weightlifting belt

The belt arrived very quickly and packaged nicely. The belt is everything I had hoped. It’s really nice that someone in Europe is stocking a high quality 3” weightlifting belt because they are extremely useful for deadlift and surprisingly difficult to find anywhere. As a matter of fact this store was the only place I found in Europe. Also, I did not to pay any additional customs fees either which is always a big “what-if” when order things from outside of Sweden. I will definitely not hesitate ordering from this store again.

Get them while you can

Got these to keep my knees warm during strongman training-I’ve had my knee rebuilt twice and it’s susceptible to pain! I already have various 5, 7 and 9mm sleeves, and a set of the newer gen ‘competition’ grade, super stiff neoprene (AMAZING but not great for moving around in).
These are the best all rounders. Great compression, SUPERB warmth, and reversible. Size guide is bang on. I see Frank Daddy is no longer manufacturing, so grab them before they are gone forever, these would be easily worth it at double the price.

Finally a belt that works!

Over the years I've tried different belts for deadlifts and always had an issue with having sufficient support and still being able to get into position. This belt solved that!

Due to its thinner thickness and adjustability I can now lift with the support I need as the weights get higher!

DropZero Barefoot Trainer Shoes

Bought as a gift, went down very well. Now worn daily. Excellent quality. Very comfortable. Tip - Do use the size guide, there not like regular shoes.

Just love it! Good quality and nice prints.

Great product

Exactly what I was looking for - great product great service

Great Shoes / even better service and choice

Firstly the shoes are great, if you like a Nike Metcon but want something a little more comfy for day to day as well. These shoes are ace. Unique design as well so in my opinion, the look cool and standout. I’m using them from everything from squats to farmers walk and they are sturdy and more than up to the task. 9 for 9, i only discovered them on my search for a U.K. TYR retailer, but i’ve now bought 3 pairs of shoes and a selection of kinda fit apparel, top service, personal and where possible i will
continue to support this U.K. company. We all need to if we want access to a better selection of brands in U.K.

KFKF Big Fat Sleepy sticker

What can I say....a really fun sticker that now proudly adorns my work laptop. My daughter loves Pokemon, and I love kettlebells, so this was a no brainer. Postage was a little steep but I have nothing bad to say about 9for9.

Love it!

I'm a little worried, my t shirt collection is slowly becoming only kinda fit kinda fat!

The quality and cut of the t shirts are great!

Throw in the fantastic customer service, it's hard for me to resist picking up more.


Ive used dowins for an age, wanted to upgrade and was attracted by the wide toe box. These shoes are light, comfortable and stable. The heel height is perfect , I can get them nice and tight but by the end of a session, im still comfortable. I took advice and went fully one size up which is just right. Customer service is, as always, excellent

Excellent service

Fast service! Great communication throughout. Highly recommended.

I Love Stickers!!!

Great design and I love it!

Kinda Fit Kinda Fat Thicquila Tee (Red)

Absolutely love the products
Will be buying more
Emma thank you for the message ♥️

Love TYR Lifters and Fantastic service too.

I bought the L1 Squat University TYR lifters. I'm so happy with them. Had to go up half size which is perfect fit. They are comfortable in the toe box as wide enough to spread out toes and snug enough without being too tight. I had the best service and advice too. Prompt delivery. I wil be returning customer for sure. Highly recommend TYR and 9 for 9.

Absolutely love these t shirts. Slightly pricey but I do keep coming back.
One slight bug bare though, they do go bobbley quite quickly.

A Must

If like me you’re sick of bloody shins or bad form from trying not to get bloody shins, these are a must, comfy and do exactly what you want them to do!

A plus

Love the Junk brand and 9for9 service is brilliant. I keep coming back for more and I know it is safe, supporting small business, and quick.

Pioneer Cut Powerlifting Belt – 10mm/13mm thick – 3"/4" wide (Treated Leather)

Best belt

Great product I definitely recommend People buy this belt I personally think for it quality and price it the best belt you can get really happy outstanding product

Quick delivery

Very happy with my order, quick delivery and the items ordered were out of stock on the offices website so very happy to find it here

An incredible belt

I picked up this 4"/13mm belt last month to help prep for a competition later this year. Since getting it I have breezed through my heavy lifts - the amount of confidence this belt gives me is amazing.

Having the double line of holes is mega useful as it lets me customise exactly how tight I want to wear it, and I've never found myself wishing for anything different.

Emma was super friendly and helpful, aiding me when I wasn't sure which size to get. Thanks 9for9!

Excellent Company and Customer Service

T-Shirt is great quality.

Had a great experience with 9for9, had a delivery issue but they were quick to respond and chase down the problem. Excellent.


I LOVE this hoodie. So comfy, well finished and great quality material, loving the logo too. Washes well and dries quickly. I wish there were more like this I could buy!
