Post It Note Sizes Explained – Which Size Do You Need?

Choosing the right Post It Notes can make everyday tasks quicker and more organised. Whether you're leaving reminders, marking documents, planning projects or creating meeting notes, selecting the correct size helps ensure your notes are clear, practical and easy to use.

At Office 5 Star, we supply a wide range of 3M Post-it® Notes, sticky notes and repositionable note pads in a variety of sizes and colours to suit every workplace.

Why Does Post It Note Size Matter?

Different tasks require different note sizes. Below are the most popular sizes.

A small note is perfect for marking pages or leaving a brief reminder, while a larger note provides enough space for detailed messages, meeting actions or project planning. In addition to the small Post it Notes there are Post it Flags too for page marking.

Choosing the right size not only improves organisation but also reduces clutter and helps important information stand out.

Small Post It Notes – 38mm x 51mm (1.5" x 2")

Small Post It Notes are ideal for:

• Page markers

• Quick reminders

• Price labels

• Short messages

• Highlighting important documents

Their compact size makes them perfect when only a few words are needed.

Popular uses:

• Marking contracts

• Flagging pages

• Filing reminders

• Temporary labels

Medium Square Post It Notes – 76mm x 76mm (3" x 3")

This is the classic Post-it® Note size and remains the most popular choice for everyday office use.

Ideal for:

• Telephone messages

• To-do lists

• Daily reminders

• Desk notes

• General office communication

The larger writing area provides enough space for detailed notes while remaining compact enough for desks, monitors and filing systems.

Large Post It Notes – 76mm x 127mm (3" x 5")

Larger sticky notes are particularly useful when more writing space is required.

They are commonly used for: 

• Meeting notes

• Project planning

• Team brainstorming

• Customer instructions

• Process reminders

Many businesses use larger notes during planning sessions because they are easy to read from a distance and provide plenty of writing space.

Coloured Post It Notes

Different colours aren't just attractive—they're also practical.

Many businesses use colour coding to organise work more efficiently.

For example:

• Yellow for reminders

• Pink for urgent tasks

• Green for completed actions

• Blue for project planning

• Different colours dedicated to the note leaver

Using colours consistently makes it easier to prioritise work and locate information quickly.

Super Sticky Post It Notes

If you're placing notes on vertical surfaces such as whiteboards, walls, filing cabinets or doors, Super Sticky Post-it® Notes provide stronger adhesion while still being removable.

They're particularly useful for:

• Project planning

• Team collaboration

• Workshop sessions

• Training rooms

• Office noticeboards

Choosing the Best Post It Notes for Your Workplace

When selecting Post It Notes, consider:

• The amount of information you need to write

• Where the note will be placed

• Whether colour coding would improve organisation

• Whether standard or Super Sticky adhesive is more suitable

• Whether you prefer genuine 3M Post-it® Notes or compatible repositionable notes such as 5 Star Office or Q Connect brands

Choosing the right combination of size and adhesive helps improve organisation while making everyday office tasks more efficient.
