AmazonBuying Guide
Start by deciding between Olympic (50mm hole) and standard (25mm hole) plates — Olympic is the universal choice for serious training and resale value. For home gyms, a solid starter set includes pairs of 5kg, 10kg, 15kg, and 20kg plates. Bumper plates are essential if you do cleans, snatches, or any lift where you might drop the bar.
Pay attention to plate diameter and thickness. Full-size bumpers (450mm diameter) are necessary for proper deadlift height. Cheaper plates often have wider tolerances — a "20kg" plate might actually weigh 19.2kg or 20.8kg. If accuracy matters, invest in calibrated plates. For durability, crumb rubber bumpers handle drops better than virgin rubber on rough surfaces like garage floors.
Frequently Asked Questions
What is the difference between bumper plates and iron plates?
Bumper plates are coated in dense rubber and can be safely dropped from overhead without damaging the floor or the plate. Iron plates are bare metal (cast or machined), more compact for the same weight, and cheaper — but dropping them will crack floors and damage the plates. Most lifters use bumpers for Olympic lifts and iron for squats and bench.
How many weight plates do I need to start a home gym?
A practical starter set is 2x5kg, 2x10kg, 2x15kg, and 2x20kg — that gives you up to 120kg with a 20kg bar. Add fractional plates (0.5kg, 1.25kg, 2.5kg) for progressive overload on pressing movements. You can always buy more 20kg plates later as you get stronger.
Are calibrated plates worth the extra cost?
For competitive powerlifters, yes — calibrated plates are machined to within 10g of their stated weight, which matters in competition. For home gym training, standard plates with reasonable tolerances (±2%) are perfectly fine and much cheaper. The difference only matters if you need exact numbers for meet preparation.
Should I buy all bumper plates or a mix of bumper and iron?
A mix is the most practical and economical approach. Use bumper plates for your working sets on Olympic lifts and deadlifts (where dropping is possible), and iron change plates (2.5kg, 5kg, 10kg) to add increments. All-bumper setups get very wide on the bar at heavier loads because bumpers are thicker than iron plates.
