When dealing with the size and shape of the medal, several factors need to be taken into account to ensure that the medal is both practical and beautiful. Here are some tips on how to decide the size and shape of your medal:

### Size selection

1. ** Use and Occasion ** :
- If the medal is used for a formal award ceremony or as an important symbol of honor, a larger size (such as 70mm to 120mm in diameter) is usually chosen to reflect its importance.
- For daily events or small events, smaller sizes (e.g. 30mm to 60mm diameter) may be more appropriate, easy to carry and less costly.

2. ** Recipient ** :
- Taking into account who will wear or display the medal. For example, children's MEDALS should be smaller and lighter, while adults can accept larger designs.

3. ** Visual Effects ** :
- Larger MEDALS can accommodate more detail and information in their design, while smaller MEDALS are better suited to a clear and concise design.
- Ensure that text and patterns remain legible at the selected size.

4. ** Budget constraints ** :
- The size of the medal directly affects the amount of material used and the cost of processing, so it is necessary to plan the size according to the budget.

5. ** Packaging and Transportation ** :
- Large MEDALS may require special packaging to protect them and increase transportation costs; Smaller MEDALS are easier to handle.

### Shape design

1. ** Tradition and Innovation ** :
- Traditional round, square or oval MEDALS give a sense of stability and reliability, suitable for most occasions.
Innovative shapes (such as hearts, stars, or other geometric shapes) can add uniqueness and interest to a particular event.

2. ** Symbol Meaning ** :
- Certain shapes may have special cultural or industry symbolism, such as a snake and staff shaped medal in the medical industry, a book shape in the education field, etc.

3. ** Practicality ** :
- Consider whether the medal is easy to hold or wear. Non-standard shapes may increase the difficulty of production, but also pay attention to whether the edge will scratch the skin and other issues.

4. ** Suspension mode ** :
- The design should take into account how the medal will be fixed or suspended from a rope, chain or other pendant. Some shapes may require additional structure to support the suspension function.

5. ** Space Utilization ** :
- Irregular shapes can make better use of limited space to show complex design elements, but also ensure that the overall layout is balanced and harmonious.

### Final decision

- ** Sample review ** : If conditions permit, make one or several samples of different sizes and shapes, actually observe their effects, and make a final choice accordingly.
- ** Feedback Gathering ** : Present the design to potential recipients or other interested parties and get their input to ensure that the final product meets all expectations.

By taking these factors into account, you can choose the size and shape of the medal that best suits your needs, creating a custom medal that is both beautiful and practical.
