Each block is 21mm in height and you always need an odd number of Stackers on each side to make up a box frame. The minimum required number of blocks is 3 on each side to make up a 63mm (2.5") tall frame.
The most efficient way of purchasing these blocks is as a pack which you can find here: https://mattestlea.com/products/stackers
Use this product to top up what you've got or to help make irregular shapes (although they will be coming as packs in the near future too).
How do they work?
Slot the Stacker Blocks (the one with the hole running through it) onto the frame clamp rods before the frames are built.
Put together all the frames in their entirety (but don't stack them yet), roughly to the size of the box you'll be making.
Attach the magnetic Stacker Spacers to the Stacker Blocks.
Place your next frame with the Stacker Blocks already applied on top of those Stacker Spacers.

Can’t recommend this course enough! A great day that was packed full of learning and advice whilst feeling relaxed and welcoming. Matt is as good a host as he is a teacher and I came away with lots of things that will transfer to other joinery I’m sure.
Shout out to Rob too for showing some of the cool laser cutting process and complimenting the relaxed vibe of the day.
Can’t wait to do another course as they appear!
Dovetails in a Day - Workshop Course

These work perfectly!
These work perfectly! I had actually given up on attempting mitres with hand tools, as it was just too frustrating, but I just managed to make my first absolutely perfect mitre joint. Extremely satisfying :)
Just make sure to use a solid and strong clamp, to prevent the guide from slipping back under pressure, especially when working on hard wood. As my clamp wasn't doing the job, my solution was to place a thin anti-slip mat between workpiece and guide. This solved the problem perfectly for me.

A real piece of history! The gently curved face is a masterpiece of engineering while the feel of the mallet in my hand is nothing short of a miracle of attention to detail. It is so comfortable that it falls away into a seamless blending of body and tool.
