DL Sizes Compared

When it comes to paper sizes, most people know what A4 size is. But if you’ve ever heard of the lesser-known DL sizes, you may be wondering what exactly they are. If this is the case, then you’re in luck. We’ve put together a comprehensive guide about exactly what DL sizes are, and what they’re best used for.

What is DL paper size?

The term DL size is quite literal: DL stands for ‘dimensions lengthwise’. The dimensions lengthwise of DL paper size is 210mm. The height of DL paper size is 99mm. Card or paper that’s DL paper size is designed to fit perfectly inside an envelope and is often used for promotional materials such as brochures, flyers and leaflets.

However, things aren’t quite as simple as they seem. While paper size that is 210 mm x 99mm is commonly referred to as DL size, this is not exactly the case. the term DL size technically refers to a standard size envelope that a letter is sent in. The size of this kind of envelope is 220mm x 110mm.

So DL paper size is actually the size of paper that fits inside a DL size envelope. Regardless, the term DL size paper is commonly used to describe the paper size that goes inside the envelope. If one was referring to an envelope of DL size, they would call it a DL size envelope.

To help you get your head around it and envision the size of DL size paper – it’s the same size as exactly one third of an A4 piece – like when A4 size paper is folded in thirds to fit inside an envelope. It’s often used for smaller flyers or invitations that don’t require an entire A4 piece of paper to include all the information required.

DL size paper often looks a lot more elegant, sleek and professional than a larger piece of paper that’s folded up to fit inside an envelope. Plus, if the piece of content or graphic that’s being printed and distributed in high volumes, a smaller size like DL size paper can save the trader on printing costs significantly, in comparison to printing on a larger size.

Some materials that are commonly printed on DL paper sizes:

DL Envelope

As mentioned above, DL size envelopes fit DL size paper. They are not the same size, otherwise DL size paper wouldn’t be able to easily slide inside the envelope. DL envelope sizes are standard sized envelopes and allow adequate room for the paper to easily fit inside. While envelope sizes do vary depending on what you’re sending, the most common size of standard personal envelopes is DL size.

We offer standard DL sized envelopes that are customisable to add your brand’s identity. These envelopes are 220mm x 110mm, made of quality 100 GSM laser paper and offer a window or windowless option.

With compliments slips

With compliments slips are extremely popular in the business world – most offices have a large stack of them and use them to jot down a quick note and slip them into envelopes along with other things they are sending. A with compliments slip is normally handwritten and commonly sent with something like a brochure to add a personal touch to the mail.

A with compliments slip will normally have a business name and logo prominently featured on it, so the receiver can easily recognise where the note is coming from. These slips are typical DL paper size – 210mm x 99mm – so they slide easily into a standard envelope.

We offer with compliments slips. We have an online system where you can easily upload your own custom artwork or brand logo to print on the slips. The slips are  210mm × 99mm and are printed on high-quality 100GSM stock. It’s also possible to print on both sides of the slips.


Flyers are usually an unfolded document that promotes a brand, product or service. They are a great marketing tactic to raise awareness about your business and – when done correctly – can help to build your brand and increase revenue. Essentially, flyers are used for advertising, so it’s important to make sure they look as sleek and professional as possible so that it reflects well on your brand.

We offer completely customisable DL size flyers that can smoothly fit into a standard size envelope. Our easy-to-use online program lets you upload the flyer that you’ve designed. From here, you have some customisations options, like the quality of the print, whether you want single-sided or double-sided and whether you’d prefer a matt of glossy finish. These flyers are typical DL paper size – 210mm x 99mm.


Ever since the rise of the internet, typical holiday postcards have become less popular. However, postcards are now used for other types of documents – like invitations. They’re also often used as a more personal way to advertise a business or product. The thickness of a postcard separates it from a flyer, as its usually made of a thicker card.

We offer a service to make personalised postcards. The cards are printed on thick 350GSM card and can be single sided or double sided, and have a gloss or matt finish. The size is 210mm x 99mm. The upload process is easy – simply upload one (for single sided) or two (for double sided) designs on our website and we can take care of the rest.


Brochures are a luxurious looking marketing material that usually has more detail than a standard flyer. When a brochure is flattened out, it is the same size as A4 paper. However, the information is printed over three columns, which makes for a more interesting layout and more text without the page looking too content-dominated.

We offer a brochure printing service. If you’re overwhelmed about where to start when designing a brochure, not to worry – we offer customisable templates too. We have an extensive range of options available for events and industry-specific layouts.

If you’re already got a design in mind, you can go ahead and upload it. If you’d prefer to use a template, you can browse our options and then add in the information that’s specific to your business. Our brochures can be single or double sided, and can be printed on gloss or matt paper.
