ASIC Dimensions, Weight & Shipping-Class Reference
D-Central’s open reference for the physical dimensions, weight and shipping basis of Bitcoin ASIC miners and single-board hardware — length x width x height (mm), net weight (kg), cooling type, the computed volumetric (dimensional) weight and which weight a carrier bills on. Grounded in the D-Central spec registry and cross-checked against manufacturer spec sheets.
Quick answer
This reference lists the physical size and weight of 23 Bitcoin ASIC miners and single-board units — the Antminer S9 (350x135x158 mm, 4.2 kg), S17 (298x178x296 mm, 9.5 kg), the S19 / S21 / T21 family (the standard 400x195x290 mm air chassis, ~13-15.4 kg), the S19 XP / S21 Hydro water-cooled units (410x170x209 mm, no chassis fans), MicroBT WhatsMiner M30S/M50S/M60S (390-430x155x226-240 mm, ~12-14 kg), Canaan Avalon A13/A14 (360x170x282 mm, ~12.6-12.8 kg), the open-source Bitaxe single-board (envelope approximate), and the D-Central Bitcoin Space Heater builds. Each row gives L x W x H in millimetres, net weight in kilograms, the computed bare-unit volumetric (dimensional) weight, and which weight governs the carrier charge.
For every full ASIC here, the carrier bills by ACTUAL weight — net weight (~12-15 kg) always exceeds the bare-unit volumetric weight (~3-5 kg), so a freight quote built on dimensional weight will under-charge. Free CSV/JSON under CC BY 4.0. Honest scope: gross/carton shipping weights are not manufacturer-published and are flagged "unverified"; Bitaxe board envelopes are approximate and enclosure-dependent. Net weights vary +/-1 kg by revision and exclude any external PSU — always weigh and measure the actual packed unit before quoting a carrier.

Grounded in the D-Central dc_miner spec registry and cross-checked against manufacturer spec sheets — gross/carton weights are flagged "unverified" rather than guessed, and the volumetric weight is computed (L x W x H in cm / 5000). Pairs with the universal ASIC miner spec database, the connector pinout reference and the shipping policy. Always weigh and measure the actual packed unit before quoting freight.
