Complete guide for buying Keepfiling binders

Whether you are shopping online or at a store for binders, sometimes it can be overwhelming with the large selection available. There are so many different sizes available, and even if you know what size you need, there are still choices to be made in terms of what material is the binder made of, or what rings they use. It's not an easy task.

  1. Size
  2. Rings
  3. Materials

1. Size

Size does matter. It important to make sure that your binder can fit the papers you are planning to organize or archive. Using the right size binder will make sure your papers are protected. If you're organizing letter size paper then you will want a letter size binder, or if it's legal size paper then a legal size binder, and so forth. You don't want something smaller because the papers won't fit, and you don't necessary want something bigger either because even though it will protect your paper, it will be hard to handle the binder or it can be a waste of space when you're shelving them.

Having the right size is also important especially if you decide to use sheet protectors. For example, technically you can store letter size paper in a legal size binder because the binder is big enough to fit them. However, you will not be able to find letter size sheet protectors that will fit into the legal size binder.

It's important to have the right size binder for your paper.


2. Rings

It's a very common mistake for consumers to think that the capacity of a binder is based on the width of the binder spine; the wider it is, the more paper it can hold - that is wrong. The correct way to determine a binder's capacity is to actually look at the ring size.

Here is a table showing roughly the capacity a binder can hold with different ring sizes.

O-rings
Ring Size Paper Capacity1 Sheet Capacity2
1/2" 75 25
3/4" 125 45
1" 175 60
1-1/2" 250 90
2" 350 125
3" 570 200
D-rings
Ring Size Paper Capacity1 Sheet Capacity2
1/2" 95 35
3/4" 145 50
1" 195 70
1-1/2" 270 95
2" 370 130
3" 590 210

Keepfiling D-Ring
All Keepfiling binders use D-rings

A part from ring size, there is also ring type that you need to consider and the sizes of these rings are measure different. There are two types of rings - O-rings and D-rings. For O-rings, the ring size refers to the diameter of the ring. The wider the diameter, the more it can hold. For D-rings, the ring size refers to the height of the straight part of the ring. The longer the straight part is, the more it can hold. D-rings are sometimes offered in a slight angle, and they are called slanted D-rings.

Another small difference between the two rings is that O-rings are mounted onto the binder spine, while D-rings are onto the back cover of the binder which allows paper to lie flat. Some people prefer this as they think it looks nice and is more organized. All Keepfiling binders are equipped with D-rings to offer a more uniform look for organizing papers.


3. Materials

What material is the binder made of is also an important factor you must consider when evaluating your options. Different materials fit different purposes. Today, manufacturers make binders from all sorts of materials to satisfy different needs and tastes from consumers. They can range from traditional paper or cardboard binders, to more durable ones made from plastics, or fancier ones made from fabric.

In most cases, typical binders you find today are made with some plastic like polypropylene, and some cardboard. They will use cardboard as the core and cover it with PVC plastic, and then complete the rest of the binder with other similar plastics. These types of binders are usually the more durable type and will last you longer. They are used everywhere from offices, to homes, or at school.

For fancier looks, there are binders with covers that has a print on them. These binders are often called "turned edge binders". These binders are also made with a cardboard core but instead of covering it with plastic, it is covered with paper. Usually a layer of lacquer is applied onto the paper for a glossy finish and also as a added layer of protection for the binder. Sometimes these binders are made with just cardboard, without the paper cover. These binders are not as durable and will often split open at the bottom because it lacks the extra covering provided by the paper cover, if it had one. Keepfiling binder covers will not split.

Keepfiling Binders

Despite all the options available for binders mentioned above, Keepfiling have made is easy for you to purchase just the right binder for your needs. All you need to know is the size of the documents you're keeping in the binder.

All Keepfiling binders are made with polypropylene and uses 1-1/2" D-rings. Instead of offering them in different materials like cardboard, fabric, or metals, we believe polypropylene is the most economical in the long run; best value for your money. It is durable and can be made in different colors for style. We've chosen to use D-rings because of the uniformity it offers when pages are stacked together, also because they can hold up to 25% more than O-rings. This gives the binder flexibility if it wants to hold more pages for manuals or reference binders. We use 1-1/2" size because we consider its capacity to be the ideal number of pages a binder should hold because it becomes overloaded or too heavy to carry around.

With archival safe polypropylene and 1-1/2" D-rings, we think Keepfiling binders can be great for all purposes: For presentations, or as an archive binder to organize references, or even as a portfolio to showcase your artwork. We truly think of our binders can be used for multipurpose. Instead of having to buy a separate presentation or portfolio binder, just buy a Keepfiling binder to fulfill all your different needs.
