how to set max size, sometimes the generated sprite.png is too big

I think you can't. Not via options anyway. If you could though it would be in spritesmithOptions.
You can split your set of source images though, and create multiple instances of the plugin.

@mixtur same question here, and find a solution, just see see.

this line

webpack-spritesmith/src/Plugin.js

Line 94 in be950b3

const allSourceImages = Object.values(sourceImagesByFolder)

add a filter function as options of src

// Plugin.js
const allSourceImages = Object.values(sourceImagesByFolder)
                .reduce((allFiles, files) => [ ...allFiles, ...files ], [])
                .filter(x => !x.endsWith(path.sep))
+              .filter(x=> typeof this.options.src.filter === 'function' ? this.options.src.filter(x): true)

then use it in configs like

// webpack.config.js
new Spritesmith({
        src: {
            cwd: path.resolve(globals.ImageDirectory, dir),
            glob: '*.png',
            filter: (f)=>fs.statSync(f).size < 10 * 1024 // limit to less than 10kb
        },
        target: {image:{/*....*/}}
})

just solve my problem. @echolove38 have a try try...
