Buying Leather by the Square Foot

Buying leather by the square foot is not all that common. Why? Well, it’s a bit of a hassle for the vendor. They have to measure and cut leather before handing it over to you. Additionally, selling leather by the square foot has the potential to be less profitable than selling leather by the piece. 

However, as a customer, buying leather by the square foot is pretty advantageous in most cases. The best reason to buy by the square foot is, of course, buying only what you need. That can also be the tough part, but that’s what you’ve got us for!


Let’s start with measuring! It is essential to this entire operation. Leather is measured by the square foot. Why? Well, it’s a somewhat rectangular piece of material with no standard dimensions, unlike fabric. So, we sell the leather based on what’s there. The simplest way to do that is to measure it by the square foot. Because leather is not uniform, the way a square foot or ten can be taken from a piece is up to the person cutting it. That’s why it’s important to know how to measure your leather. It’ll give you a good idea of what you’ll be getting and it will help you determine whether or not you’ve received the proper amount. 

Calculating Square Feet

Allow us to give out a quick and complimentary math lesson. Multiply the length of your leather by the width of your leather and, you’ve got your square footage. So, if your leather is 3 feet long and 4 feet wide, you’ve got 12 square feet of leather. You’ll often see sites with pre-cuts that are 12in x 12in – that’s one square foot! Compare that price to the leather you’re considering and you might save yourself some dough. 

So, how much do you need?

You know how to measure, but now you’ve got to buy the leather. A pattern or set of instructions will give you an amount of leather to buy, but we always recommend buying a bit extra. Why? Because even master craftsfolks make mistakes and you don’t want to run the risk of a vendor running out of the leather you need before your project is done. We recommend buying 20 – 25% more leather than you think you’ll need. So, if you have a project that calls for 12 square feet of leather, we recommend getting 15 square feet. That gives you wiggle room for blunders, cutting around imperfections and testing out tooling, dyes and paints. 

The Shape of your Leather 

The final thing to note is that at SLC “quantity” is measured by the square foot, so if you enter “1” in the quantity box, you’ll get one square foot. Of course, this doesn’t apply to pre-cuts or other products that are not priced by the square foot. Whatever quantity you choose will likely not yield a perfectly square piece of leather. We’d have a lot of waste then. Your leather will be in whatever usable shape we can get the right amount out of. If you’re looking for squares or rectangles or even circles, you’ll most definitely want to buy a pre-cut. Below is a chart of different ways your leather could be cut. Pieces are most likely to come out like the 2 sq ft piece on the far left. 

Top Marks – Grading Veg Tan

Join Kevin for an in-depth discussion about vegetable tanned leather. He discusses vegetable tan quality and vegetable tan grading, plus a bit about the Springfield Leather way of classifying leather – it’s a great way to know what to expect! 


Many newcomers and even some more experienced people in the leather world are confused when it comes to the grading and quality of leather.  I thought I’d try to make a small effort to clear it up a bit….

When considering actual “quality” of leather, “A grade, B grade, C grade, D grade, (and lower) are all the same when it comes to tooling and carving


You see, when the tanner gets the hides in, they’re a bit nasty. They’re covered with salt, and hair and other things, and this prevents him from knowing what sort of hides he has. So, until the hides go through the dehairing and tanning process, he won’t know its quality.  Once the hides come out of the tanning pits, then they have to be dried, ironed, split, rolled, and go through a host of other processes. In the case of Hermann Oak, since all the hides are tanned together in the same pits, the leathers that come out are all the same quality of tan.  (By the way, Hermann Oak is the only one using the old pressed-yard tanning method, so tanning quality will likely vary more from other sources.)  


After the skins go through myriad steps to become leather, they move on to the final stage: trimming and grading.  At this point, all the sides are full weight, and pretty rough looking around the edges.   Most veg tanners only use one or two people to do the grading and trimming of sides, so as to maintain maximum uniformity.  We’ll talk about trimming first:   Trimming is the act of cutting away all the little undesirable tatters and ugly areas around the outer edges of the side.  The person that does this either saves the tanner lots of money, or costs them lots of money.  He has to try to achieve a very delicate balance here…. He’s charged with making the side look good when it’s “set out”, while at the same time not removing any more valuable footage than absolutely necessary.


Keep in mind that tanners make money on volume of square feet processed.  So, if the trimmer removes ½ a sq ft from 700 sides in a day, the tanner loses 350 sq ft per day.  Let’s just say that his average cost for all leather in the tannery averages out to $4 per ft.  Multiply that $4 by 26 production days in a month, and you get a very large number!   So the more skilled the trimmer is, the more money the tanner makes!  The less skilled the trimmer is, the more money the tanner loses!  

Grading Criteria

Usually the trimmer and the grader are the same person.  So, when the trimming is done, he begins the grading process. 


The person doing the grading looks for cuts, open scratches, open scars, healed scars and brands, surface grain damage, soft spots on the back of the hide, stains, scud (leftover hair), machine damage, the depths of the “pockets” (armpit areas) and other various irregularities. 

The bottom line is that the grader is primarily concerned with cosmetic issues. The grader obviously cannot see into the leather.  He also is not going to wet a spot on the side, make a few cuts with a swivel knife, then bevel a little to see how it cuts or tools. Those things are not able to be detected by the tanner, or by us. One problem that can occur in the tanning process is when the tanning liquor does not fully penetrate an area of a skin.  This is extremely rare, but can and will happen over time. As a vendor, all I can do is work with you on getting a piece of leather that doesn’t have a defect, of course, we won’t know until you try it out! Working together in these instances is all that we can do. 

Grading Systems

Some tanners use A, B, C, D, x, xx, xxx to denote grades. Others use a number system. At SLC, we use a grading system that places “A”  at the top of the quality scale as letter grading generally matches up to tannery grading systems like Hermann Oak. Lower grade sides will have more of those cosmetic issues we mentioned and higher grades will have less, but the leather itself is all the same quality. 

The tanner will get maybe 5-10 “A” grade hides out of 100. Maybe 20 or so “B” grades.  The rest will be “C”s, and “D”s.  

Something that most crafters are not aware of, is that to a tanner, an “A” grade side is simply the best grade of leather that is in the tannery at the moment.  That’s why you can still find an occasional defect on an “A” grade side.  So, if you order 50 sides of “A” grade from a tanner, you’ll get the best 50 that he has, even though some could have been “B”s in another run. 

Buying by the Grade

For what it’s worth, we sell more lower grade Hermann Oak veg sides than all other grades combined.  One reason is that most people realize that not only is it less expensive, but also they can cut around most cosmetic issues, or use them in a place where they won’t be seen or affect the integrity of their project.  An example would be a knife sheath.  You could put a piece with a scar on it on the inside of the sheath, and it would not be visible, or affect the quality of the sheath.  On the other hand, if you need large areas that are very clean, then “B” grade sides would obviously be a better option.  But here’s something to think about:

If you have a large D grade side that has a nasty brand as large as a man’s hand in the center of the butt area, and a hole large enough to push a volley ball thru around the shoulder, it would naturally be a lower grade side.  But if there were no other defects, what do you think would be the grade of all the rest of the leather in that side?  You guessed it…. “A” grade!


That’s also why, if for example, a customer ordered “D” grade leather from us but all we have in stock is “B” grade leather, we’ll send that customer “B” grade leather! The danger of course comes when the customer thinks that all “D” grade leather is as good as the “B” that he actually received. Normally we’d tell the customer about the swap, but sometimes things like that go unnoticed. Knowing the difference for yourself is always helpful.

All in all, considering what cowhides have to go through to become leather, I think we’re pretty fortunate that we even have leather!  And now you know how quality of leather and grading of leather go together!

The bottom line: buy your leather from someone with experience that you trust and have a good feeling for, and be as reasonable with them as you want them to be with you.
