Before exploring custom options, it’s essential to know the standard sizes in our planter box factory’s catalog. These pre-designed dimensions are optimized for mass production, cost-efficiency, and quick delivery, making them ideal for most landscaping, gardening, and architectural projects. Below is a detailed breakdown of the sizes we regularly stock, categorized by shape and application.

1. Rectangular Planter Boxes (most popular):

- Small: 12 inches (length) x 6 inches (width) x 6 inches (height) – perfect for herbs or small succulents.

- Medium: 24 inches x 8 inches x 8 inches – fits windowsills and narrow balconies.

- Large: 36 inches x 12 inches x 12 inches – standard for raised garden beds.

All standard products are available in multiple materials (cedar, pressure-treated wood, powder-coated metal, food-safe HDPE) with optional drainage holes. If a dimension from our inventory fits your design brief, you can order directly without waiting for a custom quote — and still adjust minor features like color or corner style. Should your project require a non-standard length, width, or unique shape, our custom department can modify any of these base sizes, but starting from a proven standard keeps both cost and lead time low. I recommend reviewing this catalog list first; many clients find the “medium-large rectangular” or “square 18” category meets 90% of their needs. Let me know which size interests you, and I’ll provide pricing and material samples.
