When designing an outdoor square, the choice of floor tiles is crucial. Floor tiles not only affect the overall beauty, but also have an impact on the use, maintenance and cleaning. Therefore, it is very important to choose the appropriate size of the outdoor paving tiles. The following will introduce you to the general size of the outdoor paving tiles and the factors that need to be considered when choosing.

1. Selection of specifications and sizes
The size of the outdoor paving tiles is usually determined by the size of the square, design style, use function and other factors.
Common specifications include:
- 300x600mm: This is a smaller size floor tile, suitable for small outdoor squares or places where complex patterns need to be laid.
- 600x600mm: This is a more common size, suitable for medium sized outdoor squares, easy to lay and easy to clean daily.
- 800x800mm: For larger outdoor squares, floor tiles of this size are more suitable to create a broader visual effect.

2. Factors to consider
When choosing the size of the specification, you also need to consider the following factors:
- Square size: The larger the square, the larger the size of the paving tiles will generally be chosen to reduce the seams and create a unified aesthetic.
- Design style: Different design styles are suitable for different sizes of floor tiles, which need to be selected according to the overall style.
- Use function: If the square needs to often bear the load of vehicles or large objects, it is necessary to choose wear-resistant and pressure-resistant large-size floor tiles.
- Cleaning and maintenance: Different specifications and sizes will also affect the difficulty of daily cleaning and maintenance, which needs to be considered comprehensively.

3. Other suggestions
In addition to the specifications and dimensions, the following recommendations should also be noted:
- Color matching: When selecting floor tiles, color matching with the vegetation and architectural style of the surrounding environment creates a harmonious and unified visual effect.
- Material selection: Outdoor square should choose weather-resistant, wear-resistant floor tile materials, such as granite, ceramics, etc.
