Set tile size

Control tile dimensions using the size parameter to set output image resolution.

Choose a tile size based on your use case:

Standard displays - Use 256×256 for optimal performance and bandwidth
High-resolution screens - Use 512×512 and set scale=2 for sharper rendering on retina displays with higher DPI
Print maps - Request larger tiles for higher quality output
Performance tuning - Balance image quality against file size and load time

Syntax

You can adjust the tile size through the size parameter that supports the following values: size=256 or size=512. If you do not specify tile size, the default value is 256×256 pixels.

Size	Dimensions	File size	Best for
`256`	256×256 px	Smaller	Standard displays, mobile
`512`	512×512 px	Larger	Retina displays, print

Examples

The following examples demonstrate how to request different tile sizes with the size parameter:

Standard size (256×256)

The following request shows how to get a standard-size tile. You get the same result when you explicitly specify the size parameter with the value of 512.

Large size (512×512)

To get a 512x512 pixel tile, set the size parameter to 512, as shown in the following example:

GET https://maps.hereapi.com/v3/base/mc/15/16376/10896/png?size=512&style=explore.satellite.day&apiKey={YOUR_API_KEY}
